GeoTREE provides ArcSLAMM workshops

Posted Oct. 20, 2016, 6:57 a.m.

The UNI GeoTREE Center (John DeGroote and Research Assistants Garrett Jepsen and Aaron Padilla) and collaborator Rebecca Kauten provided three workshops in Ankeny, Dubuque, and Coralville. Approximately 40 attendees from local government (e.g. cities of Cedar Rapids, Dubuque, Coralville) watershed management and education groups (e.g. Easter Lake Watershed and Dry Run Creek Watershed Coordinators), and private engineering companies (e.g. Shive-Hattery, RDG Planning & Design). The workshops highlighted work the GeoTREE Center is doing under an Iowa Department of Agriculture and Land Stewardship grant to highlight custom ArcGIS tools the GeoTREE Center has developed for working with an urban stormwater modeling software. The workshops included example applications in several watersheds. The GIS tools as well as all modeling results for watersheds in Iowa will be made publicly available.

IEDA Webinar on ISAM

Posted Sept. 8, 2016, 5:12 p.m.

John DeGroote presented a webinar in conjunction with Iowa Economic Development Authority (IEDA) Energy Office. The webinar presentation described the large data processing solar radiation modeling project the GeoTREE Center completed under an IEDA grant. The project resulted in a several order of magnitude more detailed mapping of solar radiation potential and a public facing web mapping application which can be accessed by anyone including individual property or business owners who would like to investigate solar potential of their property/building or solar installation companies who can use the application to do preliminary investigation of solar radiation potential anywhere in the state of Iowa. This web mapping application and underlying database are called the Iowa Solar Asset Mapping (ISAM) tool. The webinar was attended by individuals from academia, private companies, government agencies, and non-profit organizations.
