Geographic Information Systems (GIS) at INHS

A Geographic Information System (GIS) is an organized collection of computer hardware, software, geographic data, and personnel designed to capture, store, update, manipulate, analyze, and display all forms of geographically referenced information (data identified according to their location). This technology can be used for scientific research, resource management and planning. GIS allows users to perform very difficult, time consuming, or otherwise impractical spatial analyses quickly and efficiently.

The GIS at the Illinois Department of Natural Resources (IDNR) is a department-wide group of offices and divisions that use GIS technologies. These include: Illinois Natural History Survey, Illinois State Geological Survey, Illinois State Water Survey, Waste Management and Research Center, Illinois State Museum, IDNR Office of Mines and Minerals, IDNR Office of Realty and Environmental Planning, and IDNR Office of Resource Conservation. In the spirit of cooperation and to avoid duplication of effort, GIS data are freely shared between these offices and divisions.
The GIS group at the Illinois Natural History Survey, Center for Wildlife and Plant Ecology is made up of GIS experts with diverse scientific backgrounds, conducting research in landscape analyses that help determine the extent and condition of different community and habitat types in support of conservation policy decisions.

Far and away the most important part of any Geographic Information System is its people.
