Geological Survey

Geographic Information Section (GIS)

Responsibilities

The GIS section is responsible for the development, management, and coordination of the Department's Natural Resource Geographic Information System (NRGIS). This includes development of specific major geographically referenced databases, GIS system planning and integration with other computer systems throughout DNR, assistance to all DNR programs regarding GIS technology implementation, staff training on GIS concepts and using GIS tools, providing public access to GIS data, and external coordination with state, federal, and local government, and university and private groups regarding geospatial databases and GIS technology. The section also is responsible for acquisition of aerial photography, satellite imagery, geophysical data, topographic data, and special maps that may be required for various resource investigations.
