Geographic Information Systems (GIS)

Our GIS staff build and maintain spatial datasets and applications, conduct GIS projects, and publish GIS maps in support of the agency's mission of protecting the land, air, and waters of the state.

Tools used in our work include GIS software by Environmental Systems Research Institute (ESRI): ArcGIS, ArcSDE, and ArcGIS Server.

These pages are targeted for an audience experienced with GIS terminology and standards. If you are new to GIS, you can learn more at ESRI's GIS website.
