Mapping and GIS

Geographic Information Systems at the DNR

The GIS section is responsible for the development, management, and distribution of the Department's Natural Resource Geographic Information System (NRGIS). This includes data collection and analysis that may be required for various resource investigations and in support of making natural resource management decisions.  We deliver data in various formats to decision makers and the general public.  We also provide GIS support and training to other sections of the DNR.

What we do:

Data Collection and Production - Making good natural resource management decisions first requires good data.  There are many GIS projects that have focused on collecting and producing basic data on Iowa's natural resources.  Examples include the Iowa LiDAR Project, Geocoding Project, Historic Aerial Photography project (1930s, 1950s, 1960s, 1970s, 1980s), multiple recent statewide aerial photography collection projects (2002, 2007-10), National Wetlands Inventory update, and a statewide floodplain mapping project.

Data Analysis - Good decisions often require analysis of the available data.  Examples include our High Resolution Land Cover project, Nutrient Reduction Strategy modeling and support, National Hydrography Dataset (NHD) conflation effort, and Restorable Wetland Analysis project.

Data Distribution - GIS data is primarily delivered to natural resource managers and the public through our NRGIS Library, GIS Web Services, and Web Mapping Applications. 

     NRGIS Library - - The DNR's clearinghouse for the repository of GIS data.

     Web Services - - Live data as Web Mapping Services for use in applications.
