 Okay, good morning everyone. My name is David Rowe. I am the Director of Digital Matters and Associate Professor of English Today we're going to have a workshop led by Justin Sorensen. But before we get into that and I give my introduction to him I want to make a few announcements The Tanner Humanity Center and the College of Humanities is hosting Ruha Benjamin an associate professor of African-American studies We'll be here virtually on October 15th giving a talk on her book race after technology We have obviously have some overlapping interests with this event. So I encourage you to check that out second thing is that we have a new media studies reading group where we select a book on a Digital humanities subject broadly conceived and we read it and then we discuss afterwards We put out an announcement where we will give you a way we'll give away free books for those who are interested in participating So please if you're interested in participating in that sign up through our listserv or email Marissa Marissa if you can add your email to the chat box, that'd be great And lastly we have a series of faculty grants and graduate fellowships You probably have heard of already the deadline is tomorrow by midnight Marissa will add the links to the chat box as well And I just want to make it to trust that there are a several different Grant programs. So there is the faculty grant and then there's an exhibition slash performance grant And then there's a graduate fellowship and it's a exhibition slash performance Graduate grant. So please make sure to read up on the differences between them Okay Justin Sorensen is a GIS specialist in the Department of Creativity and Innovation Services here at the Marriott Library Some of this GIS projects include reconstructing the past through Utah Sanborn fire insurance maps and the historical GIS of Salt Lake City An interactive geospatial study of historical Environmental and health written impacts to Salt Lake City today is going to give us a very gentle crash course on GIS All right, let me go ahead and share my screen with you guys Can everybody see that okay, is it okay? Okay, so um, yeah, thank you David. Good morning, everyone. Thank you for joining us for today's Virtual workshop titled digital to physical using GIS technology to create 3d co-progressive models My name is Justin Sorensen. I'm the GIS specialist at the J. Willard Marriott Library During my time working within the GIS industry one of the things that I've enjoyed most is utilizing the power of GIS technology to take datasets To an entirely new level and that's what I'll be demonstrating for you today In this workshop, I'm going to be introducing you to an in-house process that we've developed for converting elevation data into 3d models for printing and analysis I'll also be introducing you to a new project that is in the development stages at the marriott library that allows us to Take geospatial datasets and project them onto printed topographic models So, um, do you have any questions about the processes that i'll be covering today? I'm happy to answer those for you at the end of this workshop I'll also be sharing some detailed handouts at that time So that you too can create and print 3d topographic models of areas around the world. So With that, let's go ahead and jump right into this workshop To start things off I'd briefly like to introduce you to what GIS is and why it's so important in our world today GIS is used in many aspects of our lives, whether we realize it or not Um, and really it makes a lot of the modern conveniences possible Now this can range from something as large as monitoring and implementing plans related to vegetation change over time Or something more simple that many of us view on a daily basis using our phones to find and navigate to locations around town GIS stands for geographic information systems or in some recent trends people refer to it as geospatial information systems And this represents a number of different geospatial technologies Software processes and methods for visualizing different types of data within a geospatial context Generally, this type of data is presented in the form of cartographic maps interactive mapping applications and geospatial infographics At its core GIS allows for the visualization analysis and interpretation of data in order to understand relationships patterns and trends and data The way that this is accomplished is through the incorporation of multiple layers Which when brought together creates a geospatial visualization that expresses and enhances data by incorporating visual resources Now these layers can include things such as imagery including satellite and aerial photographs elevation data sets such as contour lines and elevation models demographic data sets such as census information transportation data sets including street networks and railways address information including geocoded and flooded locations physical features including boundaries hydrology and survey control points As well as research data that is collected that an individual may wish to share with their viewers Bringing this information together provides not only an educational experience But also a method for researchers and viewers to answer questions Relate findings and identify solutions that previously may have been unconsidered In today's workshop, we'll be focusing on one particular type of GIS data that can be utilized to create 3D topographic models This type of data is known as digital elevation models or DEM as I'll be referring to it throughout this workshop The DEM is a data set that contains elevation data representing the surface or terrain of the earth That also has this unique ability of being expressed three dimensionally when the appropriate tools and procedures are applied At the level of detail that's contained within these data sets can depend on the resource that you acquire it from So to begin, I'd like to introduce you to a free openly available resource for acquiring high quality DEM data sets that can be used to produce a 3D model The resource we'll be utilizing for acquiring DEM data sets in this workshop is called the National Map Viewer An online resource provided by the United States Geological Survey or to UGS It contains a wide variety of products related to the United States For this workshop, we're going to be focusing on a single feature found within the United States But should you be interested in features found outside the United States Earth Explorer is another online resource provided by the UGS That is a great resource for acquiring such data sets When the National Map Viewer is first launched, you'll see that I'm presented with an overview map of the United States Along with a selection of available data set options to the left To identify available DEM data sets for my project, I begin by selecting elevation products 3DEP within the selection window And I narrow the selection down so that returns results In this case for a one third arc second DEM interval Now you're probably wondering what a one third DEM one third arc second DEM is Basically in a dual spatial perspective, one third data set translates to a model that has elevation changes of 10 meters So each layer of the model represents 10 meters This is one of the highest quality and most commonly available DEM data sets that are available throughout the United States When you begin working with areas outside the United States that turns into One arc second data set and that's more of elevation changes of 30 meters. So It's slightly less detailed than the 10 meter data set I'll be working with today, but it still contains a lot of valuable and useful information for creating 3D models I begin my search by identifying a single location or feature on the map that I can obtain a DEM data set for For today's workshop, I'll be showing you how to create a 3D model of Mount Rainier located in the state of Washington I began by inputting this information into the search box Which navigates me to the location on the map In the new pop-up box, I select find products to display all of the available data sets matching my search criteria In this case a single item is returned containing a one third arc segment or a 10 meter DEM data set representing the area of Mount Rainier Selecting the footprint option provides a preview of the extent that the data set covers on the map and also allows me to verify that the data set will include information on the feature or area of my focus Some additional options that are available include selecting the thumbnail option to preview how the DEM data set will appear when it is open As well as the download option to save the data set to a project folder on my computer Now a tip that I do recommend when you begin generating models from these DEM data sets is to create a new project folder for each project you're developing Doing so helps to avoid any problems with future projects that may utilize the same data set Once the DEM has been downloaded to my project folder I can unzip the file and I'm ready to take the first step towards developing my 3D model This is an example of what the DEM data set looks like It's a geotip image containing the image, elevation information, and location information for automatically overlaying in the correct location within a GIS mapping program Next step in creating a 3D topographic model from a DEM data set is to clip the original downloaded DEM into a specified area, shape, or extent Now this step is completely optional and you can't proceed forward with printing the entire downloaded DEM But you will find that when printing such a large extent, physical details are less visible So I do recommend that you proceed with this process and refine the model into a more focused, detailed, and presentable model of a specific area or feature So in this example, I'll be clipping the DEM to contain only data surrounding the immediate extent of Mount Rainier Which, as you can see, is a very small portion of this downloaded data set To perform this process, you will need access to a version of ArcGIS software Either ArcMap or ArcPro, which is the version that I'll be using for this example Access to both these software programs is available on Patriot computers located at the Marriott Library's Knowledge Commons, University of Utah Computing Labs, and remotely through the CSBS Virtual Lab using your unit name and password As the DEM contains no references to distinguished individual features from, I begin by selecting an appropriate base map for this project I recommend choosing either an imagery with labels base map or a general topographic base map as these will assist in identifying specific areas and features that are found on the map With the reference base map in place, I bring the downloaded DEM into ArcGIS Pro using the add beta tool within the map pulls ribbon at the top of the screen And navigating to the file within the project folder As you can see, once the DEM is added to ArcGIS Pro, it automatically overlays in its appropriate location on the map It also becomes a selectable layer within the table of contents located on the left side of the screen I also have the option to zoom into the layer should it not be so automatically by right clicking on the layer within the table of contents and selecting zoom to layer I then want to adjust the transparency of the DEM layer in order to see both the physical features and references found in the base map as well as the DEM itself By going to the appearance ribbon at the top of the screen and adjusting the transparency slider so that both the base map and DEM are viewable simultaneously And generally what I found is a good reference for this is around 32-40% so I'm putting 30% on this example here Viewing the area directly above the downloaded DEM, I use reference information contained within the base map to identify the area representing Mount Rainier And zoom in for a closer view by hovering over the feature and using the mouse wheel to zoom in I'm now ready to create a shape that represents the extent of Mount Rainier for my model To do this, I begin by creating a feature class that will be used to create a boundary for the DEM features to be clipped The boundary itself can be anything as simple as a circle surrounding the feature, which is what I'll be demonstrating next Choose something a bit more complex like a county or state boundary I begin by going to the catalog panel located on the right side of the screen Navigating to my project folder and right clicking on the associated geodatabase folder and selecting new and feature class Using the feature class tool Using the feature class tool, I input information to create a polygon representing the boundary shape Since I'm only creating a single feature for clipping, there's no need to create large amounts of attribute data for the dataset So I can select okay and complete this process where I can drag and drop this new feature class into the table of contents panel that I just created To create the boundary feature itself I highlight the feature class layer that I just created within the table of contents And within the edit ribbon at the top of the screen, I select create features I want to create a basic shape surrounding Mount Rainier So I select the circle option within the sidebar and select the tool itself within the mapping window Left clicking on the center of Mount Rainier. I drag the circle outward to my desired extent left clicking again to complete the shape Back in the edit ribbon at the top of the screen I select save edits and the new boundary shape is ready to be used to clip the DEM dataset With this boundary layer in place, I'll now click the DEM to export only features representing Mount Rainier contained within that circle To do this, I go to the analysis ribbon at the top of the screen and select tools In the new search window, I search for the clip raster tool and select it from the available options Within the new processing tool window, I input the DEM layer as a layer to be clipped The feature class layer as the boundary to clip features within I name the new DEM file and select both extent boxes then choose run When the process is completed, you'll see that a new clip DEM has been created containing only data representing Mount Rainier within the boundary circle It is this new clip dataset that will be used to generate the detailed 3d model of Mount Rainier for printing and analysis With this export process completed, I can close ArcGIS Pro and move forward to the next step And that next step in the 3d topographic model process is to convert the clip DEM dataset into an actual 3d model Or an SDL file that will be used to generate the final model To do this, you'll need access to a program called QGIS A free, openly available software program available for download from the QGIS website Now unlike ArcGIS Pro, QGIS has one particular tool that was missing for generating a 3d model Called DEM 3d printing I begin the process by opening QGIS Navigating to the new clip DEM dataset and adding it to my QGIS project In the raster menu at the top of the screen, I select DEM to 3d and choose DEM 3d printing In the new processing tool window, I'll input the size and layer information that will be used to generate the 3d model For this process, I'll apply the following information based on specifications for the Marriott Library's task set across the printers For extent, I select Print Full Extent And what this means is that I want to print the entire extent of my clip model as you can see with This red dashboard surrounding the model so I know that this full area is what will be printed For print spacing or how thick I want each layer to be, I want these to be on the thinner slide So I'll select 0.2 millimeters But depending on the detail and the type of model you're working with, I sometimes even reduce this further to 0.15 or 0.1 millimeters For dimensions, I want my model to be the maximum size of the print bed So for the Tata 6 printers, this is about 11 inches or 279.4 millimeters But other printers available at the Marriott Library, such as the Gigabot printer Can print up to a maximum of 24 inches or 609.6 millimeters For the exaggeration field, I want to make sure to emphasize peaks that are found in my model So I'll increase this to anywhere from 1.2 to 1.5 But I have found that anything above 1.5 will distort the features and won't present an accurate representation of what's found in the real world Finally, for height, I input the lowest point indicated in the provided elevation data to the right From here, I select export to SDL Making sure to maintain the default file name for the export The reason that I Sorry, the reason that I say to maintain that default file name is that this avoids a common error that causes the model export process to fail But after the process is completed, you can go back and rename the file name afterward Now depending on the file size the size of your model output and the processing power of your computer This process can take some time to complete But once completed you can open the new model file in a preview program such as print 3d That's found on the windows platform to make sure that everything looks good before closing qgs And what you're seeing on screen now is just an example of what that exported model looks like within print 3d Gives you a good idea of how the model Looks if you can see any features that you want to change before you move on in the process and just a good overview of the model itself Now with the 3d model now generated. We're ready. We're really in the home stretch I'll now use an additional program to convert the 3d model from its sdl file into a code that the 3d printer Will use to put the final model Now there are many programs available to perform this process But the one that i'll be using for this workshop is called prusa slicer It's another free and openly available program that you can find and download from their website This program along with another program called cura are also available on dedicated model slicing machines Computers located in the proto space area of level two at the marriott library Uh, those machines also are preset with information on the available 3d printers that are found in the same space So for this process i'll go into slicer and begin adding the x by exporting the I'll begin by adding the export 3d model that I created in the previous step Utilizing the available tools within slicer. I can apply changes to the final model including adjustments to the overall scale Removal of additional material that was generated during the export process And other features that are available as well In this example, I am actually removing the square border that is surrounding the model So that the final output contains a circular model representation of not right here Once i'm satisfied with the appearance of the final model. I select the slice now tool to begin generating the layers of the model to be printed Now this process is very interesting as it provides an interactive preview of each layer of the printed model and an overall understanding of how the printing process will proceed Once the slicing process is completed. I select export gcode and save the file to my project folder It's this gcode file that will be loaded onto the 3d printer and used to create a printed model of matt rainier After reviewing the return information on size print time and print filament requirements I can close slicer and move on to the printing my 3d graphic model So we have the gcode the final model is ready to go. We're now ready to begin the 3d print The printing process can be as simple as finding a 3d printer such as those located in proto space Loading the exported gcode onto the printer's sd card Loading some printing filament onto the printer itself and selecting print What you end up with is something like this a detailed model of matt rainier created using the processes covered in today's workshop and printed on a machine located at the marriott library The marriott library has a number of lot of 3d printers available for use by students staff and faculty at the university of utah with expert staff on hand to assist in answer questions Pictures of the model in the slides and actually I'm going to hold it up for you the actual model itself that you're seeing through my webcam Really don't do it justice Unless you see it in person But as you can see in these images and what I'm holding here the model itself really is quite detailed and provides a very good representation of how matt rainier is found within the real world So and no, it's it's pretty light easy to work with so Now as you begin developing your own 3d topographic models It's important to know that experts at the marriott library are available to support the development of your project and assist with questions that you have along the way Should you require assistance generating topographic models? I'm happy to help provide a one-on-one consultation to support and help you understand the model generation process Or resolve any issues you experience in its development And those consultations can be scheduled by visiting the gis services website Additionally our expert staff in 3d printing services are available to assist with the model slicing process and any issues experienced using the 3d printers Additional information about those available printers and details for performing a 3d print can be found on their web page And I would also recommend visiting that page as well for any changes that may have been implemented at this time due to covid So as you've seen today dm datasets are extremely useful for creating 3d topographic models of features found around the world But the process of simply printing and examining these models is just the beginning I'd now like to introduce you to a new project in development at the marriott library The idea for this project started simple How can we combine the power of gis technology with 3d printing? The important role that gis plays has the ability to be taken to a new level Protecting various geospatial datasets directly on depended 3d models Stage one of the projection concept began in 2018 We began with simplified 3d topographic prints Now these were strictly for test purposes and we knew based on the quality output that we received that high quality Data would be needed should the project progress to a new level In these images you can see the results of our initial testants and the efforts to project gis data from google maps onto the model held projector While simplistic in its approach results proved that the possibility for projecting data onto the models was there And that the project had great potential if taken to the next level Stage two of the projection concept began in 2019 The process for acquiring exporting and converting the em datasets into customized 3d models was refined with larger highly detailed models being created In this example, you can see the large-scale wall-mounted model of solid county credited almost two feet wide with silver filament The stage two projection concept utilizes a mobile projection unit with various static images of data continuously projected on Raspberry pi computer And this is an example of that slide show in action Justin, I think we lost you Oh, looks like he dropped out. Oh, there he is. Are you back? Justin Thanks frozen Bear with us folks Hopefully he's back online soon Justin, can you hear us? I can hear you. Can you hear me? We can now or you're cutting out. I think your connection is pretty unstable While we're waiting, um, if Justin handed you You or marissa this handouts might want to we pass that out To the participants marissa. Do you have those? I don't think I have just in handouts Um, no, he's he said that he was going to distribute them Afterwards, okay You guys hear me, okay Uh, now we can You can hear okay. I'm sorry. It looks like I was booted off. I don't know what happened there Okay Okay, you can hear me. Okay. Yeah, let's give it another go Okay, I apologize for that So, um, what I was mentioning is that you can see the various layers projected onto the model while it's in action We brought different things based on like elevation census information Demographics information like that. So it's really interesting what you can do by projecting that data For the um, oh, sorry, and then here's some additional images So you can see a side angle of the solid county model The different details of different canyons the topology going on But then the image to the right you can see just how well the data that we're collecting with the gis is projecting directly onto the model So it aligns very well overall For the next stage of the project concept the projection concept Further develop and fine-tuned project is in development Currently, I've generated scale models of all 29 Utah counties and submitted them to expert Our expert 3d printing services team for large-scale printing When it's complete a large demographic model of utah with individually interconnected county tiles will be on display in the marriott library Approximately five feet by four feet in size A high quality 4k projector will be installed either on a stand or from the ceiling and project interactive gis data sets onto the large-scale model Controlled by a tablet or a computer system that patrons will have the ability to incorporate their own data sets on Now as the project is in development, it's unknown exactly when it will be deployed So I do recommend staying tuned to the marriott libraries website blog posts and the gis services webpage for more information on that as it becomes available Um with that I would like to conclude this workshop by thanking each of you for taking time to join us today And for your interest in learning more about the 3d topographic model project and services we're working on at the library Um, I hope the workshop is helpful and providing information for developing your own 3d topographic projects and ideas for applying these processes to projects you're developing on your own again, should you need assistance with developing a model or Creating a 3d print. Please feel free to reach out to me and gis services or a member of our 3d printing services team with any questions that you have um with that I will go ahead and Upload the handouts for this workshop To the chat window. Let me go ahead and do that now So while just is doing that we have time for some questions Um, and I think if you want to just type in your questions, rebecca will moderate But also if you'd like to just ask, please raise your hand either visually or with the emoticons I'll start just that. I I was trying to look for the dem data in the usgs government website I'm assuming you have it. I'm not the handout, but do What would I search for because it's a very large website and quite complicated Yeah, so um in section two of the handouts that i'm providing it tells you um What particular data set you want to be looking under in this case you're looking for that elevation product 3d ep That's what the actual file or folder that it's contained under is called And from there you just narrow it down selecting the one third arc second And that's the best high quality data that they offer at this time. So I'm sorry, what you have a link on the handout Yeah, there's a link on the handout as well And when I was mentioning earlier about one third arc second being the most high quality throughout the united states There are some areas like I think I believe in salt lake area You can get a two meter data set, but it's just not high available, you know throughout the entire nation. So one third is that available nationwide that you want to work with So we have a question in the chat. Actually, we have a couple of questions in the chat box Justin the first one is could you speak more to some of the applications you encountered of dem models? How has it been used in teaching for example? Okay um You know just a lot of them i've seen using for like elevation slope analysis You know different fields use it for different types of information This has been the major use that i've used it for so far is to use these models to create To be able to analyze different slopes different areas around the world Not really sure how others are being used or specifically in teaching But my hope is that you know with the projection system we're working on developing that This would be a use for that in a teaching environment People would be able to bring their data in projected onto models and see it actually in action So having hands-on component as well Our next question is perhaps i missed you talking about this But i'm interested to know what colors you tested for the 3d models to be projected on What the various results were and why you settled on dark gray instead of the original white? It's a good question. Um We the initial test was actually on red and let's just say red doesn't work very well for 3d Topa models Three white actually in this model that we're looking at here It works well, especially for projection But the kind of issue with it when you're looking at it from the side and stuff It's hard to see all the different You know features the details of the terrain that's going on here Silver was a very good compromise for both of them It allowed for the projection that it didn't overshadow anything You could see the different angles and shadows of the different terrains taking place on here And even when it wasn't projected it was a good reference model for working with that. So um white does work well, but Silver just seemed to stand out a lot more and catch people's attention as well Okay, thanks, um our next question Um, I'd be curious what problems you ran into during this project And also the problems that amateurs might run into when using this data and building a model Uh, one of the biggest problems we ran into was in the export process We initially tried to bypass ArcGIS pro completely just doing like the clip analysis within QGIS And for some reason or another that program just does not want to cooperate with this So that's why I highly suggest using ArcGIS pro to do clipping and stuff like that um That's kind of another thing Running into a problem is having to use multiple programs to create these models Ideally, I would like to see us just use ArcGIS pro and then go right to slicer um, I attended a GIS conference a virtual one over the summer where I actually was able to speak with people in charge at esri who created the ArcGIS program And I talked to them about this saying, you know, we we really like to see this a DM export that we can create our 3d models from So it's on their list, but unfortunately, it's not available in the current release Um, but in also in terms of what I'm going to change amateurs might run into I think it's just learning the process these steps in GIS which the handouts really line step by step So once you start mastering these processes you learn about the tools that you need to use It just helps you move forward and then you can start incorporating more things as you go down the road We have another question Justin, do you find that you lose detail when printing larger areas such as a state instead of a single mountain? Absolutely, so I mean we're looking at with the Mount Rainier. This is probably I'm going to say that's maybe five miles. I'm not really sure how far we did that But when you do a similar model that's the same size as this Mount Rainier For instance, we printed in Salt Lake County at that same size. You can see the different features like little conwood big conwood canyon But you can't really get an idea of the actual mountains themselves So like if you were to look at Mount Olympus down at the base of the canyon or something like that It you can tell there's a peak there, but you can't get all those different features like you'd be getting in a large scale. So Yeah, um, it really just depends though on what your project concept is if you're looking to do something statewide and you're not worried about, you know really fine-tuned representation of a mountain, you know Larger area works well, but for something like this, you know, you definitely want to increase that and focus on something very specific Okay, I think we have another question in the chat box Anyone else have any questions? I don't see any in here that we've missed unless there was one higher up My mistake Just and I have a question does anyone ever try to create their own data set that they would then use for gis projects? Or is it always using data that a government or someone else has already collected I haven't seen anybody try to create like dem data sets or anything like that But one of the things we do with gi services is people come in they have research data They want to create so maybe plotting locations on a map or features like Streams or old road networks or something that doesn't exist So that's the kind of things that they can come in and get helped with creating as well. So You know, it's kind of a Yeah, it's just really project-based really, but yeah, that's been kind of my experience with people working with at the university What about Oh, sorry, go ahead Uh, just one of what about non natural data sets are there like dm data sets for cities um So like getting like right down to the street level data and stuff buildings and stuff is that building? Yeah, is that right? Yeah There is a possibility to do that one of the things that we were working on testing before covid hit was working with LiDAR data so we could actually see you know an actual representation of the Like university campus what we were looking at to see how the buildings would rise in the model and stuff And there definitely is a good possibility for that. So as long as the data exists Um, it's definitely possible to create stuff like that. So But there's nothing out there already where you can just download the data like with us um For more specific data like that with LiDAR stuff you're looking at I mean the data is out there some of it is public domain and accessible others You're paying to have it done because people go through these processes to create it and are willing to sell it for subscriptions something like that Um, but yeah, I I always feel that if you can learn the process the tools to use this and create it yourself Even the better so Okay, we have another new question that came in Uh, I work with high school students interested in gis Is this something that they can access in the library even though they're not u of u students? If not, do you know of any programs or resources that they can access? Okay, um, I believe they're referring to accessing the ArcJS software within the library um I believe you could just come up to the library and use that You'd probably want to get like a visitor pass. Um, again check with um, like the library status right now for Our allowing access to the library under our current restrictions um, but um, you know There may be ways to also acquire you say you work for a high school or working with high school students Maybe there's an educational license that esri could apply and allow you to use ArcJS within those settings as well. So So can you all add Answer just by saying that in in normal times in non coronavirus times we do welcome Um anyone to come into the library and ask questions and use a lot of our resources During coronavirus because we're trying to employ social distancing and keep, you know Foot traffic to a minimum right now. You do have to have a u card to enter the library Um, and then just and I'm not sure if you kind of operate this way as well But for me when I was doing research data management services I could help community patrons if they had questions about data I just had to prioritize faculty and student projects But then if I had bandwidth I could help community members So maybe do you operate that same way with GIS where you have to prioritize faculty and students? But then are able to help community patrons Like oh, absolutely Absolutely, and you know with fact kind of the way GIS services works just to kind of give you guys an idea You know, we have a lot of faculty professors coming working on research projects. So we give them a lot of hands-on development um students and um You know graduate undergraduate students come in we help them they're working on projects in you know They need just assistance understanding processes that they're learning in class and stuff like that But I have worked with community patrons as well kind of giving them insight on the projects what's possible and stuff like that. So We have a comment in the chat box as well Um, it says, um, I feel this could be very helpful for social cartography and field work Especially to work with rural communities and just thank you. We've seen a couple. Thank yous come through Justin also awesome That comment though about doing field work in rural communities, but That's there Oh, and I like that comment right there. Esri has a bundle for school. So that's excellent to know Well, I think we're at time If there are any other questions, I'm sure Justin if you don't mind putting your email in the chat box people will email you directly Uh, and yeah, I can put it in the chat box and it's also um on the handouts themselves Um, so yeah, please feel free to reach out to me Any questions? I'm sorry. Did you already upload the handouts? Uh, yeah, I did. I can upload it again if It's on there They're in the chat box if you scroll up But I also think um marissa will probably distribute them to the digital matters listserv with a link to this recording And if you're not on the digital matters listserv, please do let us know and we'd love to add you to that So you're always aware of what events are coming up And just and just added it again. So it's at the bottom now Great, uh, thank you very much justin for the great workshop. Thanks for leading and thanks rebecca for moderating and thank you everybody for attending
