Local Foods Research and Outreach
Posted July 2, 2014, 4:41 p.m.
The UNI GeoTREE Center carried out a small research project examining local food environments as part of a 2013-14 UNI Reaching for Higher Ground grant. Spatial analyses were carried out to examine the number of people living within certain (travel - walk, drive) distances of both convenience stores and grocery stores in the Waterloo/Cedar Falls area. These results were presented to local food advocates and others including a meeting attended by a representative from Kum & Go Corporation. The research results were provided to support local grower and food advocate Chad Thomas who was attempting to convince local convenience stores to carry more local produce. In addition, results of spatial analyses were provided to a group who are investigating the opening of a food co-op in Cedar Falls who were interested in the proximity of populations around convenience and grocery stores.
Overall results of the research demonstrated that a much greater number of people live near convenience stores in the local area than do near a grocery store. For example, approximately 4 times more people live within an approximate 5 minute walk of a convenience store as compared to grocery stores (~26,000 vs. 7000). In addition, socio-demographic analyses demonstrated that populations nearer convenience stores are poorer and have higher minority percentages. In addition, the populations nearer convenience stores have a higher percentage of youth than Black Hawk County as a whole. Also based on a drive time analysis from grocery stores it can be seen that there are large areas of Waterloo and Cedar Falls which do not live close to a grocery stores. Notable areas include Northern Cedar Falls and Eastern Waterloo which have lower income populations.
A web mapping application has also been created to display proximity to grocery and convenience stores. The application can be viewed at either http://bit.ly/1q04LVR or http://univnortherniowa.maps.arcgis.com/apps/OnePane/basicviewer/index.html?appid=bfa3f88722fc4fc9bf6584faf13ef6a4. At either of these a use can turn on or off the layers.
Finally, the GeoTREE Center and UNI Geography Graduate student Matt Cooney worked, in conjunction with the UNI CEEE, on creating a web mapping application for the Buy Fresh Buy Local program. See http://www.geotree.uni.edu/temp/bfbl/.

The GeoTREE Center hosted a two-day GIS basics workshop on May 14th and 15th in the UNI Geography Department. The workshop was attended by 12 employees from city departments including Engineering, Planning & Zoning, Waste Management, Traffic Operations, and Water Works. GeoTREE student research assistants Alex Newkirk and Jonathan Beavers assisted John DeGroote in preparing and carrying out the research.
ArcSLAMM Beta Testing
Posted April 8, 2014, 3:08 p.m.
The GeoTREE Center is carrying out final testing of the ArcSLAMM package. An ArcSLAMM package has been sent to several volunteer beta testers to assist in finalizing the package. If you are also interested in carrying out beta testing send an email to firstname.lastname@example.org. Keep an eye out for the first official release of ArcSLAMM in the coming months.
New LiDAR Site Functionality
Posted April 8, 2014, 3:08 p.m.
In cooperation with the Iowa Department of Natural Resources, the GeoTREE Center (Jonathan Voss) has developed a new extension to the LiDAR data dissemination site. The new functionality allows the derivation of DEM, contour, and hillshade products for a user-defined study area. The application sends an email when these derived products are ready for download. The new tool has been added to the interface at http://www.geotree.uni.edu/lidar/. Read the information describing the new tool at http://www.geotree.uni.edu/lidar/static/derived_products_metadata.html. If any questions please contact John DeGroote at email@example.com.
Buy Fresh Buy Local
Posted Dec. 10, 2013, 4:29 p.m.
GeoTREE and Graduate Student Matt Cooney have developed a Buy Fresh Buy Local web story map for the Northeast Iowa area. See http://geotree.geog.uni.edu/temp/bfbl/. This was done in conjunction with local businesses and organizations and the UNI Center for Energy and Environmental Education.2006 2007 2008 2009 2010 2011 2012 2013 2014
