Iowa Solar Radiation Potential Mapping

Posted Feb. 22, 2016, 3:41 p.m.

 The GeoTREE Center is presently working on an Iowa Economic Development Authority Energy Office funded project. The goal of the project is to model solar radiation potential for the entire state of Iowa. The modeling utilizes Light Detection and Ranging (LiDAR) topographic data and ArcGIS Solar Radiation modeling tools. The result is modeled monthly and annual solar radiation for every location in the state. The GeoTREE Center is also developing a public facing web mapping application to display the results.

Urban Stormwater Modeling Project

Posted Feb. 22, 2016, 3:41 p.m.

As part of an Iowa Department of Agriculture and Land Stewardship project, the GeoTREE Center is working on developing databases and carrying out urban water quality/quantity modeling for several watersheds in Iowa. This work is being carried out in Indian Creek in Linn County, Catfish Creek in Dubuque County, Easter Lake in Polk County, and Storm Lake in Buena Vista County. The GeoTREE Center will use these watersheds as demonstrations projects for the use of a GIS-urban stormwater modeling system to effectively characterize urban runoff and the potential for improvements with the introduction of Best Management Practices (BMPs).

IGIC Geomentoring Project collaboration with Cedar Falls 4th Grade Teachers

Posted April 20, 2015, 4:24 p.m.

The GeoTREE Center and the Geographic Alliance of Iowa, both based in the UNI Geography Department, collaborated on a Iowa Geographic Information Council funded geomentoring mini-grant. Jacob Thiele, a senior undergraduate Social Sciences Education major, worked with GeoTREE and GAI to develop a series of story maps which were used to supplement materials being used by 4th grade teachers in the Cedar Falls School District. The story maps helped to visualize and teach regional geography of the United States. 4th grade teachers from Orchard Hill, Southdale, and Hansen Elementary schools used these story maps and found them to be useful. Some comments from 4th Grade students from Hansen Elementary included 'They help you figure out where important places are', 'the pictures help me to understand better', and 'I like how some videos, some have pictures, and others are interesting to read about'.

 GeoTREE Center student research assistants Lucie Ostlund and Alex Newkirk and Director John DeGroote attended and presented at the biannual Iowa Geographic Information Council Meeting in Pella, Iowa in April. Lucie and Alex presented a poster concerning work they have done using GIS for urban stormwater modeling in the Dry Run Creek Watershed in Cedar Falls, Iowa. John presented two half-day workshops to approximately 25 total participants from local and state agencies as well as private companies. The workshops were Beginner and Intermediate Python for ArcGIS.
