Mapping and GIS

Finding GIS Data
The GIS Section maintains a library of geospatial data available in formats accessible by a variety of GIS desktop software. Users can browse the contents of the NRGIS Library and get access to the metadata associated with the geospatial data by visiting: http://www.igsb.uiowa.edu/nrgislibx/. Within the DNR the geospatial data from the NRGIS library is accessible through a one of the departmental file shares, please contact one of the GIS staff to get access to the share. Public users of NRGIS Library data can download data directly from the NRGIS Library using a web browser of FTP client.

LiDAR
LiDAR, which stands for Light Detection and Ranging, is a new technology that creates an interactive topographic map with elevation data accurate within eight inches. Historic statewide elevation data had an accuracy of within five feet. LiDAR is a process of scanning the earth with lasers from an aircraft to obtain accurate elevations. For more information about LiDAR visit http://www.iowadnr.gov/idnr/Environment/MappingGIS/lidar.aspx
