This year due to safety concerns with the COVID-19 pandemic the Iowa Technology and Geospatial (ITAG) Conference 2020 was cancelled. Instead of the typical four-day in person event, ITAG hosted a half-day virtual event. Here is the link to the recording: https://drive.google.com/file/d/1Y31tVqT2Y2dt68kFsefBqSNOTzq0ycIj/view?usp=sharing. Below are descriptions of presentations and links to presenters’ powerpoints:
What’s New with Collector for ArcGIS
Jay Riester and Gale Shea, Seiler Geospatial
Collector for ArcGIS is an ever-evolving field app. Learn what’s new with both the iOS and Android version of Collector.
DEMs – Which One Do I Choose?
Brian Gelder, Iowa State University
The ready availability of Lidar and Phodar datasets has vastly increased the types of Digital Elevation Models that are now available. One can now generate or choose from surface models and elevation models with some having various levels of hydroflattening or hydrocorrection applied. There are also numerous algorithms which can be used to generate the different types of DEMs. So, how does one choose which one is best for the needs of one’s project? We will discuss general DEM types, the underlying assumptions, best choices for certain applications, and sources for prebuilt DEMs for the state of Iowa.
Mapping the Rural Hitch – How One Fire Department Is Utilizing GIS to Prepare for Rural Structure Fires
Adam Gebhart, Johnson County
Traveling around most urban areas, you see fire hydrants or access to a continuous water supply every few hundred feet. However, when traveling around rural portions of the state, these types of continuous water resources are rarely found. This lack of continuous water resource poses a
considerable challenge for local fire departments when responding to fires in rural areas. When a fire occurs, response time is everything. Given the considerable challenges in effectively responding to fire emergencies in rural areas, North Liberty Fire Department (NLFD) is one place utilizing GIS
technology to improve these response times. This presentation will provide background information on mapping the rural hitch to help other fire departments understand how GIS can improve their response to rural fires.
How Data “Moves” in a Versioned Enterprise Geodatabase Workflow
Nathan Teut, Cedar County
The ability to branch child versions off of other versions in a multiuser geodatabase tree structure gives us the ability to edit without stepping on each other’s toes or eating each other’s brains. This also allows QAQC protocols to be put into place when migrating those edits (reconcile and post operations) into the parent versions. To better understand these editing operations, it is necessary to understand the version tree and the concept of state IDs which can be easily viewed through SQL Server Management Studio. In a demo-based presentation, let’s go through an editing example, tracking the advancement of a zombie apocalypse upon Cedar County, by two simultaneous users, and check the state IDs to better
understand how the data “moves” from child to parent. Finally, lets quickly review the arcpy methods for automating reconcile, post, and geodatabase maintenance (rebuild, analyze, and compress operations).
Playing Nice with Your Neighbors NG911
Jeff Miller, Dubuque County
This will be a county focused meetup to discuss boundary and alignment issues between counties. For Next Gen 911 to work as expected the boundaries need to be edge matched and roads need to be connected at county boundaries.
GIS Leadership in an Organization and Best Practices for GIS Success
Matt Hoehn and Dan Haag, Esri
Esri’s Dan Haag (St Louis Region Manager) and Matt Hoehn (Account manager for Local governments in Iowa) will be presenting on lessons learned and best practices for GIS and IT professionals to use Location Technology to become leaders in their organizations. Presentation and discussion topics include; GIS and technology strategy, focusing on capabilities, establishing GIS value with business focused solutions, overcoming technology challenges, and implementing best practices.
This week marks 40 years since the Mount St. Helens eruption. The image above is from the USGS Earthshots trading card series. The images are displayed in color infrared which is useful for showing living vegetation in red. The mountains surrounding Mount St. Helens are primarily forest. Notice the extreme change in the landscape from the 1973 image to the post eruption image in 1983. The damage was extensive and ash covered much of the surrounding forest land.

Dr. Chandana Mitra of AlabamaView along with other member of her team are hosting “Mother Earth as Art”, which features USGS Earth as Art images as well as other inspired images, at the Jule Collins Smith Museum of Fine Art at Auburn University during Spring 2020. The exhibit is also available online. Here is the link to explore the exhibit: http://jcsm.auburn.edu/exhibitions/mother-earth-as-art/.
Dr. Mitra, two of her graduates students,along with the art museum curator, Christy Barlow discuss the exhibit in an online gallery talk which was presented live on Earth Day, April, 22, 2020. Here is a link to view the gallery talk: https://www.youtube.com/watch?v=UPtBDZF0DRM&feature=youtu.be
Below is a preview of the some of the images.

This Wednesday (April 22, 2020) will mark the 50th anniversary of Earth Day. While many of the large scale celebrations will have to be postponed; here are some ideas for ways to celebrate in your home or neighborhood.
#EarthDayAtHome with NASA – this website has a great collection of activities to explore our world. Here are a few that you might want check out: Terrestrial Tournament (vote for your favorite Earth images), Hit the Bricks (instructions for creating LEGO models Model 1 and Model 2), NEMO-NET (mapping coral reefs), download the ebook “Earth at Night” to view amazing images of our planet at night.
Water Rocks!, an Iowa based water education campaign, has two exciting Earth Week art contests.
1) Create a sidewalk chalk masterpiece showing your love for natural resources or ways to help protect planet Earth.
2) Gather interesting objects you find outside to create art from nature!
Check out the Water Rocks website for full details: https://www.waterrocks.org/earth-week-chalk-challenge
ISU’s Live Green Monthly Newsletter is also another resource to find ideas for celebrating Earth Day. It is filled with practical tips for living more sustainably, fun DYI Green activities, opportunities for living green as well as other interesting articles.
Have a happy Earth Day!
Just wanted to put out a reminder that the Iowa Map Contest is still going on. It’s a great opportunity for students in grades 4-12 to learn how to tell a story about Iowa’s special places using a story map. Also there are great prizes – $100 and a chance to go to the national map contest.
The 2020 Map Competition for Iowa middle and high school students is open.
Students in grades 4-12 are invited, with their teachers, to participate in this year’s mapping contest sponsored by Esri, the Iowa Geographic Information Council (IGIC), and William Penn University. This year’s theme is Mapping Iowa’s Tourist Attractions.
Contest Website: https://sites.google.com/site/iowamapcontest/home
Story Maps Website: https://www.esri.com/en-us/arcgis/products/arcgis-storymaps/overview
How to participate: Use the Story Map application to tell a story about an Iowa tourism site using a map and pictures.
Students submitting the five top middle school map entries (grades 4-8) and the five top high school map entries (grades 9-12) will receive a $100 cash prize and certificate. The top entry from each state will be submitted to the national competition hosted by Esri.
Schools must submit their winners to the state for judging by 4 p.m. on Wednesday, May 13, 2020. Iowa GIS professionals will judge the entries so Iowa awards may be announced, and send winning entries on to Esri for the national competition. Esri will announce the national winners on June 1, 2020. National winners will receive a travel grant to the Esri Education GIS Conference held in San Diego in July.
