Webinar: Convergence of Wetland Science and Technology: The Mobile Mapping Landscape

– Good afternoon and thanksfor joining us today. This is our 13th webinar in the series on the convergence oftechnology and wetland science. My name is Mike Connors. I’m the director ofcustomer success at Ecobot. Today’s conversation is going to be about themobile mapping landscape. I’m super excited to have twoof our customers with us today to share their expertise. So Callie and Scott, thanksso much for being here. We will give you a properintro in just a minute just to talk about logistics for a minute. For everyone who’sjoined, take a look down at the bottom of your Zoom window, you should see a Q&A button. Please feel free to use that. Anytime you have questions, let us know and if you’re directing a question to specifically who you’re asking and we will actuallyaddress those probably at the end of each section. And also for anyone who’s curious, we always record these webinars so if you’ve registered, you’ll get a follow-up emailto send a link to the video so you can watch this again later if you need to leave early.Our host today is JeremySchewe, co-founder and chief scientific officer at Ecobot. Jeremy, I will key to you goahead and kick things off. – Great, thanks Mike and welcome back for those of you that have participated in this monthly webinar forthe last year plus now with us and for those of you whoare here for the first time, welcome, this is a big partof Ecobot’s integration in our outstanding collaborative industry of natural resources scientists. And we love puttingthese programs together and getting wonderful guests to join us from within the industry, either as consultants or regulators or people working in NGOs or conservation based organizations and, you know, keeping things fresh and keeping a sharp eyeon where things are going in respect to wetlands and technology. So with that, I’m gonnago ahead and kick us off and with a quote, I always like to start with something that I feel like really tiesinto where we are in the now but also the stitches across time for though some of you might be aware that within the last coupleof days, the EPA has announced that it’s going to repealthe navigable water roll and that was of course implemented by our previous administration so I think we’re going tosee some interesting times ahead of us.We’re probably gonna see a lot of projects trying to be rushed into get JDS on another what is determinations. So we’re in for an interesting time but I think more than anything,I love this particular quote by Abraham Lincoln in thatwhatever we’re setting into motion is going to havea ripple effect on the future. And for those of us here asscientists or regulators, our actions, both in thefield on specific projects up to landscape level management all the way up to projects that are impacting policyand where things are going, all of that has a major ripple effect on where the generations who come after us will be able to pick up the reins and continue to run with that.And so speaking of next generations, I wanted to pull up this map here and, you know, tell a very short story of a couple summers ago, I was in Ireland. I had a couple of millennials with me and one of the guys I have, of course, still using Paper Ordnance Maps because I love paper maps. I love the way they smell. And I love just gettingall the granularity and the fact that Idon’t have to plug it in.But that sort of in juxtaposition of what we’re talking about here. The essence though, was one of these guys was literally trying to use his finger like the blue dot on anyof your GPS to like run and make guesstimates basedon where we are driving as we were trying to getout to one of our sites up in the Slemish mountains,just south of Sligo. And he kept having to recalibrate himself to like figure out, you know, like how the distancethat we’re traveling. And so it’s a fascinatingtime that we’re in where paper maps and theability to orient here is a skill that I feel isstill vitally important and that everyone should know how to do that’s doing field work. But at the same time, wehave phenomenal amount of technology that is helpingto advance our mobility and our capability tonow like track things in the geospatial landscape but also to transfer from thefield into remote conditions or into clouds or placesthat are housing data that can then affectpolicy and the building.So anyway, it’s just a littlefun story to kick us off here. This is what we’re goingto be talking about. I’m gonna do a little brief introduction for our panelists andpresenters here this afternoon or whatever it is, wherever you are. And then I’m gonna do a little briefing on GNSS receivers inrespect to mobile mapping. And then we’re gonnaspend a little bit of time doing a little bit ofa dive into the wades with a workflow inrespect to mobile mapping with a couple of differentof constellations of software and hardware with our guestpresenters here today.Put in a brief plug forour next webinar topic towards the end and thenwe will move into a Q&A. And so during that Q&A typicallywe’ll have about 20 minutes for that and so one ofthe things that I suggest for all of you as listeners, Mike already spoke to thisbriefly at the beginning, I know we’ve got more peoplehave entered the room now, down at the bottom, you’ll seeif you let your cursor hover over the screen, you’ll see a little box.This is Q&A. So if you have any questions that come up, either for myself orfor Callie or for Scott as presenters as they’re talking, like please insert them in there so that you don’t lose them. And then when we move intothe Q&A discussion at the end, I’ll curate those andeither lump them together or take them live and we’ll try to answersome of those via text. If there’s anything that’smore conversational based whether it’s for the wholepresenting group, you know, for any of our support teamhere at Ecobot, like Mike or Amelia who are on the callor in the Zoom here as well or if there’s just anything you just wanna kinda givea shout out to anyone, then you can hover overthe box at the bottom that says chat and so you can just insertthat and throw in there. So technical and questionsrelated to content focusing on Q&A, we’ll talkabout those at the end.Chat will be more justkind of rolling discussion. Yeah, so without furtherado, I want to introduce our panelists and presenters here today. We’ve got, you know, forthose of you who’ve been here in the past, you know, wehave a much smaller panel than we have had in the past and part of that is becausewe wanted to really get into the granularity ofhow things work here today not just, you know, talkabout things from a high level but a lot of what we’re gonna see is you’re gonna see some videoshares, some screen shares. What do things actually looklike when our presenters or their teams are out in thefield and collecting the data and mapping out what their findings are.So Scott Denham, some of youmay have recognized from ESI, permitting manager. He’s been a presenter onseveral other webinars over the last year and a half or so. So Scott, welcome back. Scott’s based up in thecentral Eastern part of Ohio, you know, of course my home state and really excited tohave Scott joining us here again today. And then Callie is hailing all the way in from Southern California. She’s a biologist environmentalanalyst with Dudek and we’ve only been working together for a little over amonth, month and a half but have thus far reallyenjoyed the conversations that Callie and I have been having. She really likes to get in on the taxonomy of things as well so of course I’m having a blast with her. So let’s go ahead and kick off. And first I wanna kind of frame things up from a super high level,looking at the GNSS receivers, the constellations of satellites that we’re looking at when we’re drawing upongeospatial information with those receivers and then how, of course,on a general level how that’s pairing with themobile mapping landscape.I’ve spoken to this briefly in the past but what we’re talking about here is this ecosystem revolvingaround wetland science and natural resources. We have our GIS software,whether that’s ESRI products or some of the other softwarethat people are using. We’ve got the GPS or the GNSS receivers that the field teams areusing out in the field to collect that geospatial data.And then of course we’vegot the field applications that actually allow forthe processing of the data that is necessary for anyof the regulatory reporting. And so there’s all of courseconstantly around one another, feed and nourish one another. And just as in a regularnatural landscape. So one of the things Iwanted to just touch into, here I’ve been speaking to GNSS.Some people are maybe notfamiliar with what GNSS is referring to. So GNSS is the roll-up of all of the different satellite systems that are now available on the planet. So GPS of course, is the oldest and it’s what services North America. But I believe that there’sonly 24 satellites that exist in that particular constellation. And so now we’re alsodrawing upon European, Russian, Japanese, Indiansatellite systems as well which gives us the abilityto draw on more relay points for triangulating whereour points are located. And so I just broughtup this brief GIF image that a colleague and a channel partner with Trimble Gale Shea has recently used in a couple of ourworkshops that we’ve put on with society for wetland scientists as well as Wisconsin Wetlands Association.But basically what we’relooking at here is the play, the movement, the orbitingof all the satellites around the earth and basedon where those satellites are in their orbit and where youare in your current location. Your GNSS receiver, your GPS receiver is going to be drawing, pulling down from each of the available within a site dish satellitesthat are available. And so when you are utilizing a receiver that draws from all of the constellations to the GNSS receiver, it’s giving you much betteraccuracy in terms of location because it’s not just pullingfrom our 24 GPS satellites in North America but it’s pulling from allof this constellation. All right, how does it work? How can we take a littlebit deeper dive into this? What’s the functionality of this? Here’s what you need. You need your smartphoneor you need your iPad. Some pieces of software willrequire you to have an app in order to pair to a GNSS receiver which you’ll get to see a little bit of from Scott and Callie’spresentation here shortly in terms of how thatworks, how that looks.And then of course youactually need the Bluetooth enabled receiver and then you need some sortof software application that is allowing all ofthat to be tied together so that then you can gatherthe data that you need, whether it’s just the geospatial or if it’s also the the analytical and observations that youare making out in the field. Here are some of the leadingGNSS receivers that allow us as field sciences to actually gather, submit accurate geospatial data in respect to the projectsthat we’re working on. We’re pretty excited to be in partnership with all of these organizations as well and to have multiple different companies who are utilizing variousgroupings of hardware or just all in on one or the other but pretty excited aboutwhat that looks like. And so just to kind of give you a little, again, sort of a broad level perspective of what that looks likewith the GNSS receivers, you still need to have yourinterface either with a phone or some sort of tablet thatdata can then be presented, mapped, gathered within and then exported for later use modelingand report preparation.Some of the leading elementsthat we’re gonna be talking about today of course are the three logos that you see on the screen here. So you’ve got Ecobot for the the wetlanddelineations, et cetera. And then on the additionalmobile mapping side of things, you’ve got Field Collector. I’ve got the little redline going through that just for those of youwho maybe are hearing about Field Collectortoday for your first time or just migrating into theuse of Field Collector, just know that that isgetting phased out this year and so everything’s gonna bemoving over to Field Maps. And so that’s where thingsare gonna move and look like. And so these are justsome examples, screenshots of what you’re looking atinside of these applications.And again, you’re gonnasee a little bit more of that as recorded videos fromour presenters here shortly. For those of you who arejoining us for the first time and have just heard alittle bit about Ecobot. Ecobot specifically isa hyper specific tool at this point for the wetlandsmonitoring and delineations and we’re building outadditional service areas in our current fluctuationsand roadmapping but pretty excited about the interaction and where we are growinginside the industry.Mostly what we’re hearing from people is that they’re justthey’re more competitive that they’re able to completea a higher volume of work with the same amount of team, also the ease of beingable to send data remotely from the field or to be ableto send data from field teams to GIS managers oroffice portions of teams. And then also just hearingabout higher levels of efficiency orprofitability that companies or organizations are findingwithin context as well. And so the last thing Iwant to leave you with, this is an update froma couple of months ago, showing some of the utilization and the data gathering sinceour launch in January of 2019.So here, one of thethings that’s new on here, for those of you who have seensomething similar in the past is now what we’re seeing as the blue dots are representing wetlandsample points being collected and the green points beingupland sample points. So I’m excited to see how this will grow throughout the the upcoming field season. And there we go, see that again. So I want to justtransition over into our two presenters here. So we are going to start things off with the EOS Collector, Ecobot workflow and Scott Denham from ESI isgoing to be starting us off with his presentation andhe’s going to be focused on, I believe a little bit on a threatened and endangered species workflow.So hopefully none of you willever have to use the forest to get your truck out of a wetland. All right, Scott. – Here we go. Hi, everybody. As Jeremy said, I’m Scott Denham. I work for ESI, our company’s wetlands and permitting manager. We do everything from wetland delineations to 404 or 401 permitting, T&E surveys, wetland mitigation,restoration and so forth. We’re a company out of Ohio. We have little satelliteoffices across the U.S. We’re full-time staff of about 60 and we are pretty nichebased in environmental work with just a small engineeringgroup that works with us. Keeps shifting the screen on me. We serve public to privateclients, municipalities. We do transportation projects pretty much anything youcan think of that runs into the endangered speciesact or clean water act. We’ve been through adifferent of GPS units over the course of time. We found some that haveworked the best for us in the last few years.Since I’ve been with ESI, wepair with the EOS Arrow unit. We seem to work really well with them. We range anywhere between their 100 units to their gold units just simply what you wannaget out of your data. The golden units can actuallyconnect to an RTK network so they can get you extremeaccuracy in certain areas that you can actuallyconnect to that network. We can get all the way atabout eight centimeters of accuracy actually with those units. And then majority of our staffis using the Arrow 200 units. And we pair that with a survey 1, 2, 3. At times we also majority use Collector. Now, as Jeremy mentioned, we’re shifting over to using field maps which is basically just apartner run by the same platform so it’s a seamlesstransition for the most part. And then we pair it withour iOS tablets or iPhones. The one really good thing about putting these two things together is the live mapping andbeing able to use that as you go along, you’re getting away fromhaving to take paper copies out all the time.So as you know is whenyou go out in the field, you have mud, you have rain, bugs, smudging your hand on it withsweat and everything else. It is kind of nice to have everything on your phone or on your tablet. And you can kinda zoom in and zoom out and see where you’re working in seamless Bluetooth transitioned and getting your workflow done. We do a lot of ecological assessments and we do them all over. I primarily I do themin the tri-state area. So Ohio, West Virginia, Pennsylvania. We did about a 2300 acreecological assessment. And so I’m gonna kind of show you guys what we did were there. And then also about atwo mile natural gas line in West Virginia. Just kind of comparing the two, it’s very similar data collection just kind of two differentstyles of projects for some that are mainly more energy-based versus people that aremore land development.And the purpose of thiswas to determine the extent of wetlands aquatic resourcesthat we find out there. So we did a full onwetland stream delineation and as well as since we’redoing ecological assessment, we had T&E habitat surveys. So anything that wouldhit the county lists, AIPaC, states like, sowe were running those, seeing what we needed tofind while we were out there. And also just a generalwildlife habitat study. So anything we would see, whether it was a snapping turtle, a fawn, anything like that, you know,is marked down on there. We also do land cover classifications and we do these in most of our projects. It seems to be moreand more with companies that they wanna see them, regulators seem to wanna see it more. They want to kind of classifyeverything you’re seeing while you’re out there just to give them a littlebit more background. We saw that a lot in this last year where regulators couldnot go out to sites. So they really wanted you tocapture what was out there while they were trying tolook at it via desktop.And the more that youcould explain to them, and the more that you canshow them the easier it was to get your work flow across. We use an offline data collection. You can run EOS and Arc Collector live if you have good receptionand cell reception and have a data packageto be able to use that. We tend to use an offline version so we just download the mapto the extent that we want and we go out there and we can run the mappingthat way and it’s saved and we could sync later on. That tends to workreally well then in areas that are very remote. So we can have the map, we can just kind of keep running along. Otherwise, you can kind ofrun into connectivity issues where things don’t get synced up at all. Otherwise, if you’re workingin say the city of Columbus in Ohio, you have great cellreception most of the time. You could run the map live.And in that point my GISstaff back in the office could actually watch mecollect data as I go along. So a little bit of abig brother aspect to it but they can definitelysee what I’m doing, see if I’m doing something wrong and kind of give me a calland I can adjust it if needed. The good thing about is thatit’s a very easy data output. So data collection is very easy. It brings in all your files, you geo database featureclasses, your CVS files and shape files that youcan basically just hit sync right away as soon as I’m done as soon as I have reception,as soon as I’m close to a WiFi or if I’m not runningit live, I can hit it and it can send itstraight up to my GIS staff and we can instantly pull everything down. So there’s no more pluggingit into your computer or pulling out a chip,sticking it in your computer, trying to run wires and seeingif you can get it to work, having to have a thirdparty transfer system to get it there.This is a seamless processall the way through. Just the pictures that are over there, we did a bat habitat survey andPRTs, Potential Roost Trees. That’s a running buffaloclover survey as well. And just kind of an idea of like all the different parameters that you can take while you’re out there. So this is a quick video ofbasically just connecting the EOS unit via Bluetooth to Collector – Just click on thisScott, I’ll get it running. – All right. – There you go. – And so for this, youjust need to get them within a couple of feet of each other. You can go ahead andconnect the Arrow unit to your iPad itself. It’s very easy, just like you’re connectingAirPods or anything else. EOS has this platform where you can show yourlatitude, longitude.It can show you all the satellites that you’re actually attachedto which is great then because you can see howwell your connectivity is. This one is I was sitting in my office so it says, there’s no differential but it’s great then, you cansee what your accuracy is, see if there’s something wrong, see if you need to make an update. And this is their EOSpro tools function to it. Next, then you just goright into our Collector. And what you need to do isbuild yourself a profile and make sure it’s connected.So this is just showingthat this is the Arrow unit that’s connected to it, making sure you have the right one. Those serial numbers are justright on the unit itself. And then you just make sureyou can add the receiver and so that’s the onethat you’re connected to. Once you do that, it’s veryimportant of all things to make sure that youhave a very good profile. EOS is very good with working with YouTube if you’re not really surehow you wanna do that. We build your own profile, that way you know you’rein the right network and you’re getting the mostaccuracy that you possibly can. And then you can actuallyadjust your accuracy, how you want it. If you wanna make sure you cantake things within 10 feet, you know, only a foot’cause it’ll stop you from being able to take anything then, you know, outside ofthat one foot or two feet or three feet, whateveryou decided you wanna do.Next, this is a site in Ohio that we did. We did aquatic resource delineation and T&E survey habitat survey out there. So this is just a, a quick view of kind of how we collect data, not an exhaustive version of it but just some differentthings that you can collect and pick up with this and how easy it can and howbeneficial it can be to use. This is just a project overview. If you can see all the different layers that we have on there already, different divider lines,polygons and points that are out there. It’ll kind of slide over andshow you some of the things you can collect. These are just an exampleof ones that we do. We have habitat patch points, Potential Roost Tree Locations are stream and wetland polygons and we like to color codethem a little bit different so it really stands out andyou can visually see them.And then also ittranslates to our mapping. So an example, this was justthe habitat patch point. We wanted to say, you know, classify everything that was out there, go ahead and drop our points. You can enter yourproject name, your county. There’s a bunch of different stuff on here you can have down to it. This one, we use the NCLD cover classes. So you could just say, it’s the cultivated cropsor scrubs/shrub forest, anything else that you kindasee while you’re out there and then you can go down the list. You can put as little or asmuch data as you want into it. This is a pretty largelist of data to collect. You build this and thenyou can kind of use it over and over and over and change it over the course of time.Once you do that, then how we collected is that we use a habitat divider line. And this is just a quick way of showing how you can just lock it in as you notice some of theother black lines on the screen we can box and things inand we can make polygons. And what’s really niceabout that is as you do that as long as you connect the lines, it’s a seamless polygon for your GIS. When you want to bring it downinto Arc GIS desktop or pro, it automatically then canlink these together for you. So as long as you connectthem across, you know, your study corridors or your lines then you can really showan easy habitat box out of certain areas. This was just an exampleof a Potential Roost Tree for the Indiana Bat (dog barks) or you can add inwhether it’s a live tree, dead tree, partial. Like I said, we built this in Collector. What’s really nice is thateverything that we’ve built into Collector like this andall the data that we’re taking then instantly shoots outinto tables for us to use.And we can actually take those tables and pull them out into data sheets. So instead of having havea hard copy data sheet for a lot of things thatwe wanna take out there, similar to how we use Ecobotfor wetland delineation, data sheets, we’re kindof doing on the other end but just more of like an internal way of pulling the data out. And as you can see where itsaid it was stored on device, this is ’cause the map was downloaded so all the data that we’recollecting is being stored right in this map at this in time, the map is not being run live and then later we would syncand send it to the cloud. This is an example of just picking up a perennial stream polygon. You can just kind of seehow it really breaks it out, enter in your stream names, any other information that you need for your data collection. As you build the point, it cankind of build it around it.And this is just a polygon. You can run streamlines with it as well. You can run stream pointsif you wanna do it that way. However, you want to collect your data. This seems to be kind of clean and quick and we can get measurementsoff of this as well in case for some reasonwe were out in the field and we forgot to get some measurements. If your accuracy is really good, you can take a lot ofmeasurements right off of what you’re building. And this is kind of just the final project of what things look like. You can take habitat, wildlife points. So example, this was just, you know, we found a cottontailrabbit while out there and, you know, think of whyin the world do you care for rabbits running around on the site.Well, for places likethe power siting boards and things like that, they wanna see what habitat in wildlife is using those areas. So you can create a separatepoint, put that on there. We have our NHD lines on there. We have our soil lines on there as well. So it’s basically all the mapping that you kind of need allat once at your fingertips. And you can pull allyour data down from that and you have everything thatyou need to view your site. So when you’re all done andyou have this nice pretty map with a bunch of dots and lines and points and polygons andeverything else on there, it looks kind of crazy and confusing. We get to the sync phase. And like I said, if you’rerunning live mapping then all of these, as soon asyou’re done collecting them automatically gets synced so somebody can be actuallyviewing you as you’re taking it. And we’ve tried this before. We’ve had our GIS staffwatch us collect points and see how accurate andhow well it’s going through.And it’s very good as longas you have good service, if you don’t, you have torun through this process which is just a sync phase and like I said, you’renot using an SD card. You’re not using anycords or anything else, it’s as simply gettingservice and connecting it. And so you can see thedouble arrow in the cloud and it has a little red number on it.So this is already storedon the Collector device. It’s as easy as just clickingthe up and down cloud and it’ll start downloading,it’ll start uploading. It’ll upload right up to the cloud. It’ll say complete and you can be done. Now say, you wanna get rid of your map, you don’t wanna use it, allyou have to do is manage it. You can say remove features only if you don’t want to havethose features on there. You can remove thefeatures in the base map and it will completely take that off and then you can start over. And you need to do that pretty much at the end of every time so that any data that you collect and any data somebody collectedon the same downloaded map, as as long as you both sync and then clear your map and redownload, you will see each other’s at all times so that’s very nice.If you’re running live mapping, you can just watchsomebody else collect data as you’re doing it. So when you’re all donedoing that and you sync it up and whether you are running your GIS or somebody else is doing it for you, it really does speed it up. Our team efficiency inthe field and office has been fantastic overthe last few years. As technology gets better, we try to really dive into it, just like everybody else to see how our workflow can be faster, how we can approve, howour accuracy can be.These are questionsthat we’re getting asked by clients, regulators, ourselvesof how we’re doing this, you know, and we need tohave really good accuracy. They wanna see it. And they they’re kind of expecting it now especially with all thethings that are out there. It’s nice ’cause the data transfer, it’s a direct in portraitto shapefiles in the ArcGIS. When you’re on ArcGIS on Collector, you can do ArcGIS online. You can see everything youhave collected out there. You can pull it down to ArcGIS or you can just do it liveright on the web viewer. It allows us a professional data package. We’re able to pull thesepolygons and these lines out as you can see some of themapping that I have on here. Those black divider linesas soon as they come across, we color coordinate themper different points and we can do then ourcover classes in there. And it’s just a nice cleanpicture all the way across to here’s what Newfield looks like. Here’s deciduous forest. Here’s this.Here’s a perennial streamrunning through here. Here’s a wetland running through here. And you’re able to see allthis instead of having a black and white sketch map oreven Google earth map because Google earth can be kind of, it doesn’t really show everythingyou wanna show on there or the layers don’t come out very well. So as well as you can seethe PRT data collection, this is what it spitsout when you’re all done. You collect all this data, you have this nice worksheetthen that we can pull off and use for our files orwe can leave right on there even export this into a Google earth KMZ and send this to the client and they could have all this data then if they would like thedigital version of it as well.So it’s like clean anddetailed data package for, you know, our stateand federal agency reviews. It’s definitely lesspaperwork for us in a field. And every year we have to go through the federal permit system for a lot of our T&Especies for our biologists and the cleaner everything is, we can show all these projects. We can show how manybats were being caught, how many snakes were beingcaught, things like that, how many projects that we did. And it’s really easy becausenow it’s all lined up for us and we can submit that data off and just reapp permits for each year. – Great, thank you Scott. And yeah, it’s been awesomeworking with you guys and working with EOSover the last few years and now we’re going toswitch over to Callie who’s we’ve just been workingwith for a few months, like I said, but also we’vebeen working with Trimble for a number of years as well.So we’re really excited to hear about how you guys are doingthings at Dudek, Callie. – Yeah, thank you (clearsthroat) and thank you Scott. You went over a lot ofinformation that I did not. So I’m glad that you went first so that we can kind of get a good picture of all the different optionsout there (clears throat). Let’s see here. Did you give me remote control? Yes. There we go. Okay, (laughs) it’s takinga second to catch up. Let me back up a couple of slides ’cause it just fast forwarded. Anyways, as Jeremymentioned, I’m Callie Amoaku. I work at Dudek out of ourCalifornia, Encinitas office. I do wetland delineations,jurisdictional determinations, different species surveysand write lots of reports. Dudek is a environmentalconsulting firm and engineering. We serve a variety of clients ranging from private, publicagencies, transportation, energy sectors, education, city planning, all sorts of things.And, you know, basically mypresentation doesn’t go through a case study. It just kind of talksmore about, you know, my workflow using, youknow, the R1 Collector, ESRI Collector, Ecobot and, you know, just kind ofthe getting into the leads a little bit on a couple ofthings and the possibilities and just how it helps me bemore efficient in the field and create, you know,higher quality products. I found this photo while I waslooking through some photos. And I remember when I startedworking at Dudek in 2006, we were using thesebackpack Trimble receivers and it just made me laughto think how far we’ve come.We were phasing them out at that point into kind of an olderversion of this handheld before we transferred over into this the Geo XT 6000 and 7000 and now we’re phasing into the R1 which we’re primarily using at this point. But if you’re still using these, this is a great presentation for you because you might wannaupgrade a little bit. So in addition to, you know, your typical field gearthat you would take for doing any delineation, you know, some of the things Jeremy already covered is you wanna have eitheryour phone or your tablet that has in my case, you know,we’re still using Collector. We’re phasing over to field maps but we haven’t made that move yet.So we’re still using Collector. We’ve got the R1 and theEcobot app really helps to digitize all the your field forms and get that information live without having to do, youknow, manual calculations and looking up stuff. So that’s definitelyreduces a lot of stuff you have to take in the field. And then I always havean extra battery pack because using these throughout the day really drains my battery. So really good idea to havea battery pack with you if you start moving overinto this data collection. (clears throat) And so what I really likeabout using Collector is when you’re doingyour prep for the field, you can actually ask, in my case I asked myGIS to add certain layers that I want into my app that I’m gonna be doing for that project.So for example, you know,the project boundary, obviously you want to have that in there, what kind of aerial imagery you’re using but then also things likethe NHD, NWI, you know, really helped me to kindof focus in on some areas that I wanna look at especially if I’m doinga larger project study. If you have project specific contours that can be really helpfulin kind of seeing, you know, how steep things are or where you might be able to, you know, make sure that when you’rerecording information that it’s lining up with your contours and you can kind of giveyourself a little QA/QC in the field with your receiver. If you have projectspecific vegetation mapping that’s already been done,you could look for, you know, different right pairing communities and you could just specifically add those.Or if you have regionalvegetation mapping, you know, you could use that as kindof a general guide as well. So what I like to do is, you know, ask GIS to add all the different layers that I want to have available to me in the field on Collector. And then when I’m in the office, I can draw, you know, differentpoints of target areas that I wanna visit, things like that. So I find that to be really helpful and then step over this kind of in detail. But you can eitherdownload your map offline if you’re working in a remote area or, you know, you can keep it online if you are gonna have, youknow, decent reception. So those are just kind of some decisions that you need to make basedon where your project site is. And then just making sure thatyou have all of the features that you wanna be ableto collect in the field.This is just a very simplified version kind of focusing in on theJD, but obviously, you know, you can have tons of different points, polygons, lines for whateverfeatures you wanna collect. I really like havingthe photo point in there so that it really helps me, you know, not having to download photos,remember where I took them, geo tag them in Googleearth and label them. That’s probably one ofmy most favorite parts about Collector (clears throat). So once you’re set up in the field, you’ve paired your device,you know, you’re connected and this is just a little video over here, kind of showing, you know,how to actually, you know, add your receiver. Jeremy already went, I’m sorry, Scott already went over this so, you know, we’re good on that but it does help you just, you know, if you’ve never used this just kind of understanding the workflow.There’s a couple of littlethings you need to do and then this will updateonce you are, you know, it’s getting all the different satellites and connecting them at allto increase the accuracy. Okay, so another thingthat you can customize in your settings is theaccuracy like Scott said. So if you wanna ensure thesubmeter accuracy, you know, you can go into thesettings (clears throat), you can update it with whateverinches, feet, you know, whatever the distance is thatyou want for your accuracy.And like he said, it will not collect data if you don’t have that accuracy. The other thing you cando is set your photo size. You can set your streaming intervals. I like to have it at one secondso that it’s very precise but if you have a larger area, you know, you might be able to do somethinglike every five seconds. The more data it collects,obviously, the larger file it is. So that’s kind of where thatcomes into play (clear throat).Let’s go to the next page, All right, so once you’reall set up in the field, you collect your sample points, you can add your pointseither to Collector or you can add them directly into Ecobot, kind of depends on whatworkflow you’re using. You’ve determined your wetland boundaries. You know, I put a coupleof screenshots up here from the Ecobot app becauseI like that, you know, it’s much easier to just kind of see all of your informationimmediately, you know, once you collect it and, you know, really have todouble-check too much stuff while you’re in the field.So, you know, you’ve got your wetland, you’ve got your line whereyou’re out of your wetland. And then I have a coupleexamples on the next page of, you know, just howpeople can collect data. These are not case studiesbut they are some examples. Sorry, I have a littlebit of a delay here. So this one is just anexample of how you can stream. So this would be similarto using the Geo XT where you’ve created your file and you’re walking along your wetland or along your channel, you know, whatever it is that you wanna collect. So you start streaming and you know this is just a quick example.This is in my backyard. This is not how I wouldactually create a polygon but just kind of wantingto give you an example of what it looked like to stream. You can start and stop streaming if you need to pause it. You know, maybe you haveto walk around something and, you know, startcollecting on the other side. So again, similar to the Geo XT but you actually have your aerial map that you can use to kindof check where you are which I think is super helpful. All right, so I think weget the gist of that one. And then the other optionis, if you say, for example, you’ve streamed a polygon but you come to an areawhere you don’t have access, you know maybe it’s fenced off, or there’s a bunch of poison Oak or there’s water that youdon’t really wanna wade through because you don’t have any equipment or, you know, whatever the situation is. But you have a good view on the area of where you couldmanually add those points. So this is just an example of how you can manuallyadd points in Collector to create your polygon.And then I purposely dida little mess up here to show how you can undo a point if you add something whereyou don’t want it to be without having to startover your entire polygon. So you can go in and say delete that point and then continue your mapping. And then these fieldsare all customizable. So, you know, you canhave the different fields that you wanna collect. Again, those will beexported into a table. As Scott mentioned, you canhave dropdown lists in here to you know, kind ofstreamline your QA/QC. You can have required fields. You can have fields that arenot, you know, not required. It really depends on your project.And you know how youwanna collect that data, what you want the outputto look like, you know, collecting as much data in here really reduces the the backend time that you spend kind ofQA/QCing your products. And then you submit it. This is an example of, you know, online. So if you were working offline, it would be the same workflow. It’s just that in this example, you know, your information would then be available to your other team members or your GIS staff back at the office. Similar to Ecobot, youcan duplicate your data so if you want to duplicate a point, you’ve already filled outa bunch of your information in the project and youdon’t wanna refill it out every single time, you can duplicate it, add a new location andthen just edit, you know, maybe your number or, you know, whatever thingis specific to that point. So in this example, you know, I’m just updating my sample point and you know maybe myhydrology is yes, here. So I’m gonna go ahead and change that.But otherwise I didn’t really have to fill out my name, date, projectnumber, things like that. And, you know, when you’reready to view the data again, you know, if you’re working online, it’s pretty much immediately available. So if I have, you know,say a hundred acres or so project site and I have a team that started on one end and I started on the other and we’re kind of working together then I can see how muchprogress they’ve made because their data is live.Or if you’re both thinking, well, okay, it doesn’treally work the same as working offline in order to be able tosee each other’s data, you both have to syncand do some other things. But if you’re working online then you can see whereeverybody’s working, what data they’ve collected so far. You can, you know tell your GIS staff, “Hey, we’ve collected some data, you can start, QA/QCing seeing it.” You know, kind of however, you know, it depends on how fastyou need to review things while you’re in the field versuswhile you’re in the office. And then there’s acouple different options to review your data. So ArcGIS has a Collector desktop version which will sync immediately to your data that’s either collected online or once you’ve synced and,you know, you’ve synced, you’re offline thenit’ll also pull that up.And so if you wanna go in and look at where you’vecollected, what you’ve collected if you wanna just editit at all, you know, maybe you remember you wanted to adjust one of the vertices alittle bit here or there, you wanna just make sure that you’ve checked everything out or you just wanna ingeneral view, you know, the different things thatsomebody has collected on your project site then you could do thatin the Collector app. And then another option is a geo portal which is a lot moresimilar to using Arc Maps.It’s just a, you know, youdon’t need a license to use this so you can set up a geo portal, you could have thisavailable to your client if they like to review your data or, you know, see what you’ve collected. And what I like about it is that it has this option where you can kind of see everything in what would be similarto an Excel format. So if you click on this little triangle, it’ll pull up all the differentdata that you’ve collected on the different layers thatyou have in your geo portal. And so, for example, Ican look at, you know, this polygon over here, I can see what we’ve mappedit as and I can edit these if I wanna add someadditional information here, I can do that. You can also do a little bit of editing to the feature itself. Again, if you, you know,needed to adjust something here or there.So those are some different options. And then obviously, youknow, you’ve got your Arc Map in, you know, the ESRI license that will have all ofthis information in it. But these are just kindof more user-friendly for non GIS people. All right, let’s get to thenext page maybe (giggles). So a couple of the benefitsthat I just wanted to go over, I think Scott mentioned a lot of these and showed some great examples. But, you know, it really reducesthat post-processing time. (laughs) Hold on, we’ve gone a little too far. Okay, gotcha. One more, okay, there we go. So, all right, sorry guys. So one of the things that I like is that I don’t have to go intothe office to sync my data. I don’t have to plug in my GPS unit, go into Pathfinder, downloadit, save it into a folder, tell GIS, okay, here’syour data that’s available. I can do all of that (clearsthroat) just on my phone or my tablet.And I can also review what it looks like. So that way, you know, I don’t know if you’ve ever had bad satellites and you have like that one point that’s just like a hundred feetoff of your, you know, line that wasn’t meant to bethere (clears throat). You don’t really have todeal with those things. So it makes the QA/QC a lot faster and the cleanup a lot faster. And you’ve got your datalinked to your layers, you know, in a more customizable way than what you’re really ableto do with the other receivers. I like it because it allowsme to have more preparation when I’m in the field. So I can really make sure that I’m doing a 100% thorough job. And it reduces me having to go back out in the field a lot whenI’m able to do that. I can, you know, again,like we’ve mentioned, you can have a lot morecollaboration with your team in the field to see whereyou guys are working, in the office if you havea really quick turnaround and you need to be able to say, okay, I’m done with this section.Now I need you guys to go and QA/QC it or now you can go and create a field map or preliminary map to show the client what they have on their site, you know, you can do things like that. You can have the geo portalsthat set up for a client if they wanna kind ofbe looking at, you know, what you’re mapping in real time, you know, there’s a lot ofdifferent options for that.So I think overall, it justhelps me be more efficient and helps to have higher quality products. Yeah, like other peoplehave mentioned, you know, it reduces the amount ofpaper products that you have and note taking, dealing with, you know, rain ruining your notes, things like that. You know, you just kind of eliminates a lot of those troublesome things. And then my last slide is justa little bit of a, you know, for fun, if you knowin a couple of minutes when it progresses to that slide. – How about I just steal thecontrol back and just do it? There we go. – There we go. So I don’t know if you can see the bottom but it says that, “Searching for wetlands in Southern California.” So we don’t have a lot ofthose down here (giggles). We have a little bit morecomplicated areas down here. But that’s the end of my presentation and I will be availablefor questions at the end.- Great, thank you Callieand thank you Scott. Both just great granulardives into the details in this and just a great reminder thatwe are in the 21st century and our industry is reallygonna see an upswing in our capabilities andin the ensuing year. So just a little plug for July. We’ll be meeting on July21st, fish and wildlife and the army Corps ofengineers will be joining us. We’re gonna talk a littlebit about the AIPaC and the the whole process of beginning, a section seven, section 10 and other well-armed projectsas well within that context.So we’re all excited and hopeto have you join us then. This is not a picture that I took but my wife and I dohave hellbenders living on our stream here in our property in Highlands, North Carolina. So I do wanna just goahead and segue over. We are pretty much at the top of our hour. If you can stick around for a few minutes. It looks like there’s a handfulof questions in the Q&A. So I’m gonna just jump outof the screen share here and take a look at someof the questions we have coming through. So, you know, let’s see multiple questions on the Arrow Arc Collector. What is the zoom resolutionof the map screen.Does it require a subscription? Can multiple individualswork on the same map? So maybe Scott, you wannaaddress Chuck’s question there. – Yeah, you can actuallyset your zoom resolution almost as high as you want to. It only hurts your download size. So if you’re going todownload a large map offline, the more you zoom in, the bigger the data file is going to be so it may not actually download enough for your iPad or iPhone,it’s actually hold it. But you can get city block. I mean, you can get zoomed in really well within a couple of feet.When you zoom in too much on it, you tend to jump around quite a bit more than you think. Multiple people can workon a map at the same time. If it’s a live map,multiple people can work on it and you can seeeach other’s data points as they’re getting placed down. However, there’s also achance for overlap too. So you just want to make sure that like your data’s notoverlapping somebody else’s data at the same time. Additionally, we’ve hadupwards of 25 people working on the same map at one time.We’re not necessarily workingin the exact same location but even if we are, I cansplit a stream in half. I could have one persontake the first 50 feet and streamline that way and Ican have somebody else stream the other 50 feet the other way. It still gets synced together the same way so at the very endeveryone syncs their data and it gets put in andwe can pull it down. The only thing you wanna watchout for is when that happens, is that if I collect something on a stream and somebody else collectsthe same data on the stream right on top of me, if I sync first and they sync after me, it’s only gonna showtheir data on top of mine.You’d have to kind of goback and find where mine went but there is a layer of authority where like their datacould come on top of it. But you can run and set upto upwards as many people as you want on the map at a time. – Great, and then Scottwhile you’re on there, Cynthia has asked,roughly what you’re paying per staff member to havean EOS run on Arc Collector on a per month or per year basis.- So EOS themselves other thanbuying the actual receiver, there is no subscription for anything that we’re using for them. So after you buy the GPSreceiver then it’s your receiver. They range from about$1,800 to about $5,000. The higher up you want to go and don’t necessarily quoteme exactly those costs but somewhere around in that range, I think the 200 units are around 2000 and maybe $3,500 or4,000 for the gold units.They have differentlevels of what you can buy and purchase from them. Once you purchase it, it’s yours so we run 100 to 200 gold units. So we have a lot of different ones. There’s no software packageto run EOS, EOS pro tools and is downloadable for freethen once you have the unit. As far as Arc Collector, I believe we have almost50 or 60 licenses. I’m not sure exactly what each license is. I know that we bought a bulklicense and it comes down.So maybe Jeremy orCallie has a better idea but I know that we have about five or six Arc desktop accounts but then you can run asmany as you wanna pay for basically ArcGIS. And I think, you can seeit right on their site when you look up on there too, I think it gives you their pricing. – Great, thanks Scott. So Callie, I wanna jump over to you and kinda continue in thevein that Chuck was asking about in respect toresolution with, you know, are you seeing anythingdifferent than what Scott’s seen in the utilization of theR1 with Collector and yeah? – No, I think we haveabout the same experience using R1 versus Collector. You know, there’s a coupledifferent options for R1s. They range, I think usually around $2,500 for the ones that I’ve looked at. I don’t do any of the purchasing. We have ArcGIS staff that does that. Unfortunately I can’tanswer questions on costs. I don’t know how much ourArcGIS Collector costs either.I’m sorry, I did notprepare for that question but I think like Scott said, you know, you can find the prices pretty quickly. In terms of accuracy, youknow, it’s the same thing, essentially if you’re downloading offline, the more you wanna zoomin the larger your file is and then sometimes you have to download, you know, multiple areas becauseyou’re zooming in so close so you may not be able to, you know, capture such a largearea for your offline map but you can download, youknow, multiple offline maps to work in and then in that way it givesyou a greater resolution. And then the same thing,if you’re working online, it really depends on the, you know, base layer that you’re using oftentimes so that we don’t bog downour systems too much, we will have a specific app created that clips the aerial imageryto our project boundary or maybe just outsideof our project boundary and then that way we can have, you know, higher resolution withouthaving such a huge, you know, map that’s gonna take up so much space when you have it on your phone.There was a question, well, I’ll let you carry the questions. – Yeah, so Mike Peterson asked a question about the R1 respect toutilization under heavy canopy, you know, I’ve used theR1 and the EOS Arrow and my experience with the R1is under denser canopy cover, it does lose some of itsgranularity or its accuracy. I mean, in most cases I findit’s still accurate enough for what I would be working with but do you wanna addressthat Callie as well? – Yeah, I definitely findthat it loses its accuracy when it’s under canopy. So I either have toincrease my, you know, limit on the accuracy from saysubmeter to, you know, a couple of meters or that’s when I like to kind of pair it with… Why did you go dark Jeremy (laughs)? I like to pair it with, you know, maybe contours that we havespecific for that project. So I can look a littlebit more into, you know, like if I say my projecthas two foot contours and my accuracy is six foot onthat R1 for under that canopy then I might tweak the data a little bit to be more aligned with the contours.But yeah, I find it to be similar to some of those Geo XTswhere you lose a little bit of the resolution in those circumstances. – Okay, and so one of the other things, my guess there now, I use field maps and Collector just basicallyfor the background shapefiles. I’m not actuallycollecting any data in it. But one of the things Mikewas asking is about, you know, the draw on the battery, you know, like I’m mostly using Ecobot and the processing on that’s super low. And so it doesn’t drawon the battery very much. What are you finding? And have you found any solutions other than just carrying theextra power packs with you? – I always turn mine on the low battery kind of the battery conservation which helps prolong it a little bit. If I have my phone out in the field, the battery is gonna be drained probably within half of a dayif I don’t recharge it.But if you have an iPad whichhas a much larger battery compared to the phone thenI find that those, you know, you can use those for alittle bit longer, you know, you might get a full day outof it, depending on, you know, if you’re really streaming,you know, multiple apps for the entire day, youmight need to recharge that. But if you’re using a phone, you’ll definitely need to recharge it. Yeah, the only thing really is just, you can minimize, youknow, maybe how long. If you’re driving between sites,you can obviously recharge, you know, in your car but Ialways have a battery pack with me because it drains my battery. – Great, so there’s two questions I wanna pair together here. One’s from Gates whichsounds like he’s hailing from down in the Galvestondistrict in Texas and also Steven Hoffman.So, you know, one of the things in here asking about the GNSS metadata when logging in these applications. I mean, I know that Ecobotand field maps as well as a lot of these pairing apps that we can use with these GNSS receivers let’s you know when you’rereaching the necessary peek for, but I don’t know, Scott do you wanna talk about that a little bit.I mean, I know thatwe’ve been able to meet all of those needs for Galvestonjust within the context of Ecobot when paired with but what would you add to that? – Yeah, I would say it’s the same. The GNSS metadata is, Imean, readily available. You can pull it and you can see it. Like I said, we’ve had clients, we’ve had districts ask us for accuracy especially when doing likesome stream restoration things. They wanna see how accurate everything is. We had to show them the specific points are eight centimeters, these are this. I mean, we’ve had to basically hand them all our data through. Yeah, we’ve been able to meet that.I think that is actually one of the things that these companies, theypride themselves on too is being able to like full disclosure show like that here’s the data,here’s what you’re collecting. Biggest thing is just making sure that like your collection profile, things are set up appropriately so that when you’re collecting this data, it is how you want it and it’sdefinitely set up that way for you to be able to do that. – Great, Callie, you wannaadd anything to that? – Nope, I think, I mean, usuallyif I need to get that data, I just asked GIS to downloadthe metadata for that. But again, you cancustomize it to make sure that you’re only collecting data that is with whatever yourparameters are as well.- All right so let’s piggyback off of that with Stephen’s question here. Are the post-processing of that GPS data in these particular workflows. I mean to me, that’s oneof the most exciting parts about this, but Steven’s asking are you using RTK networks? How does it work when you’re offline? So why don’t we start with you, Callie and then we’ll go back to Scott. – Can someone tell me what RTK network is? – Okay, so it’s basically, yeah, well, so maybe, you know, the easiest answer is just really Steven is that we’re not having todo all of that post-processing because there’s corrections are being made and it’s relaying off of basestations as you’re recording, especially with these settings that Callie and Scottare talking about here that you can set up in advance so that it’s only recording data when those parameters are being met.- Yeah, okay, so yeah, whereas before, when we would download the GPS data, our GIS team would thencorrect it using the latest… Okay, so I think I understand. I know that that occurs soagain, I’m not a GIS expert. We have our own team that does that. But it sounds like that is what I get. So as Jeremy said, it’s kindof doing all those corrections, you know, more in real time so we’re not having to post-process it.We haven’t had to do that sinceswitching over to Collector and pairing it with the R1s, we haven’t had to dopost-processing corrections. As far as I know, I guess Iwould have to double check with our team, but I don’t believe there is that post-processingthat occurs in there. Maybe Scott could weigh in on that. – Yeah, as far as post-processing goes, the idea is that thereis no post-processing. I mean, that’s their goal. And even talking like in a long detail with EOS and before eventalking with Trimble, that the idea is thatyou’re trying to limit the amount of post-processing because it’s actually a greater risk of manipulating yourdata in the wrong way. I mean, there’s a chance that you could actuallyover-correct, under correct data. Yeah, with the RTK networks,Real-Time Kinematic, it’s basically a bunch of base stations, a big network wherethere’s taken survey data from numerous different people. It’s highly accurate, mostlyit’s high-end survey data. When you can connect to those, we’ve only connected to themlive using live mapping.And a lot of times your bigcities, things like that, there’s a ton of data andyou’re able to connect to them. Some allow you to actuallyconnect to these networks for free. You can just log in, subscribe and they’ll kind of count you in. Others, they make you pay, you know, X amount for a month to runthe network and in being there and for some of your projectsit might be worth it.And it just allows it to correctitself down to a, you know, better accuracy while you’re out there whereas when you’re out, as you’re saying, you’re only allowed to take data in the parameters in which you have set. So if you’re kind of outside of that or you’re not really hitting satellites, you might have to wait a little bit longer to let it come down. But once you pull the data back, it’s autocorrecting,self-correcting as it gets going. The post-process is simply to make sure that your data that you collected, whatever you typed in ormaybe the lines that you drew and polygons that you did,look visibly appealing and make sure it’s theright data that you’ve had. But as far as data correctionfrom the satellites, there’s no post-processing to it. – Yeah, that’s great. And so, you know, we’re, we’realmost 15 minutes over here so I do want to kind of route us off so everybody can go back to your days.One thing I do wanna polish on here, Chuck had been asking questions about replacing the Trimble Geo 7X. So Chuck, I don’t knowif you’re in Gale Shea’s on the background ofthis conversation as well and she can certainly help you out with some of the information there. But in respect to output, I mean, yes, the outputsfrom these are our GIS files, but, you know, with ESRI products now, it’s very easy to exporta shapefile packet as you know, DXF or DWG packet. I mean, Scott, you guys probablydo that pretty frequently especially with your utility projects you guys are working on. – Yeah, yeah, it’s reallyeasy to pull it over. Nobody, yeah, nobody wants just a KMZ and they want this shapefiles pulled down and mostly we’re sending to engineers and they want those files and it’s really easy tous to convert it over. – Great, Scott, Callie, thankyou again for jumping on. We had a lot of greattechnical questions here so really appreciate you all jumping in and the presentations thatyou made were very helpful and look forward toconnecting with you all soon.And for those of you whostuck it out with us, thanks for sticking outfor an extra 15 minutes. Hopefully what we provided you with today, gave you some more helpfulinformation along the way with where things are going. And we will look to see you next time back here on the convergence of wetland science and technology. So take care everybody. – Bye..
