When: Tuesday, October 15, 2019 Where: GIS Teaching Lab, Room 248, Durham Center, Iowa State University, Ames, Iowa
This year the ISU GIS Facility in collaboration with IowaView will be celebrating Earth Observation Day. This year the theme is “Geoscience is Everywhere.” We have a great day planned.
To start out our day at 10:30am, Professor Peter Wolter will share how he is using remote sensing to measure forest structure and composition. Then we will have a Humanitarian Open Street Map Event 11am-12:30pm. No experience is needed. First, we will have an Iowa-Focused activity 11:00am-11:45am and then we will focus our efforts on an international Humanitarian OpenStreetMap activity from 11:45am-12:30pm. We will also have pizza and you are encouraged to try our new puzzles.
Obscured from view by vegetation and built structures, Iowa’s often subtle landforms are revealed through a LiDAR-derived bare earth digital elevation model in a Geographic Information System. Geological and human made features can be seen in this series of LiDAR color hillshade maps from across the State.
elevated linear ridges in this map are erosional geological features called
Paha and are found primarily in east-central Iowa along major river valleys.
This spring, Gregg Hadish of USDA Natural Resource Conservation Service and staff member of ISU GIS Facility put together a series of images called Iowa Landforms Revealed. The project looks at Iowa geological features using LiDAR. Gregg also used interesting color ramps to give these images an artistic component, inspired by the USGS Earth as Art project. The initial project includes a series of 4 images which debuted at the Iowa Technology And Geospatial (ITAG) Conference in West Des Moines, Iowa, this summer. We will be highlighting each image over the next several weeks as a special series feature on the IowaView blog. Please feel free to leave comments or suggestion for future landforms for us to explore.
The ISU Geographic Information Systems (GIS) Facility and IowaView will be hosting an Earth Observation Day celebration on Tuesday, October 15 (10:30 a.m. – 12:30 p.m., 248 Durham). We will have a speaker discussing remote sensing research. Then we will host a mapathon with pizza from 11:00 to 12:30, we will be working to add additional data to the Iowa OpenStreetMap basemap and then working on a humanitarian mapping project in an area hit by a recent natural disaster.
Are you new to remote sensing? Are you moving from using ArcGIS Desktop to ArcGIS Pro? Would you like to learn how to better use E-Cognition?
Jarlath O’Neil-Dunne, a professor at University of Vermont and the Director of Spatial Analysis Laboratory has produced an amazing collection of videos which range in scope for those just beginning in remote sensing and GIS to advanced topics and demonstrations.
Are you interested in learning more about GIS in Iowa or getting connected with other GIS professionals in Iowa? Consider attending the Iowa Geographic Information Council (IGIC) Quarterly meeting in Des Moines, Iowa. Click herefor more information.
Gregg Hadish gave a great presentation about the Iowa Geographic Map Server to celebrate Earth Observation Day. It was a hands-on demonstration of the Iowa Geographic Map Server ArcGIS App which meant participants could follow along as he explained the various features and functions of the map server. Gregg also showed participants how to leverage map server layers within their own ArcGIS Online organizational accounts and basics for creating their own apps.
Thank you, Gregg for a great demo!
Here are some pictures from our Earth Observation Day event.

IowaView, in collaboration with ISU GIS Facility and AmericaView, will be hosting the annual Earth Observation Day celebration, Tuesday, October 16, 2018, in Durham 248 from 12:15 to 1pm as part of Earth Science Week. This year, Gregg Hadish, a staff member of ISU GIS Facility and Iowa NRCS will be our featured speaker; he will give a hands-on demo of the Iowa Geographic Map Server (http://ortho.gis.iastate.edu/.) Iowa Geographic Map Server is browser-based website for statewide Iowa imagery. Gregg has been involved with the development of the Iowa Geographic Map Server for nearly twenty years. The presentation will highlight recent innovations to the map server including an updated interface as well as many new features and image services.
Iowa Geographic Map Server hosts statewide Iowa imagery dating back to the 1930s through spring 2018 as well as layers of elevation data (Lidar hillshade, contours), high-resolution land cover data, and historical data including the 1880s General Land Office maps and Andreas Atlas. Many of the layers are available as web services within GIS software. This is one of the most robust, publicly available, spatial imagery datasets in the country. This treasure trove of Iowa imagery that is waiting to be incorporated into your research. This workshop is for all levels. There will also be time for questions. If you plan to come, please RSVP with firstname.lastname@example.org as computer space is limited.
On June 27, 2018, IowaView hosted another workshop as part of the state 4-H conference. This workshop provided 4-Hers with an introduction to world of GIS. Students experienced using ArcGIS Online (an online mapping tool) to explore European migration. Next they used ArcGIS Pro to work in groups to design a neighborhood park. Finally, the 4-Hers looked at several examples of Story Maps (seen below).
IowaView hosted a workshop on June 26, 2018 as part of the annual State 4-H Conference. The workshop provided 4-Hers with an introduction to OpenStreetMap and online mapping for community service and humanitarian aid purposes.
The workshop began with an introductory lecture and then students completed two projects. The first project was mapping in Glidden, Iowa. IowaView partnered with ISU Geospatial Extension to help them improve the OSM basemap by creating more complete data for streets, sidewalks, alleys, parks, and crosswalks as part of a community planning project. The 4-Hers were encouraged to use Google street view in addition to the OSM imagery to get better views of the sidewalks and crosswalks which can often be obstructed by trees.
The group also had a short time to work on a project with the Humanitarian OpenStreetMap team helping map buildings in Osaka, Japan as part of their earthquake recovery efforts.
