Alaska State Geo-spatial Data Clearinghouse (ASGDC) provides the community with access to online maps, Data on CDs, and secure GIS data by State agency.  The Alaska State Geo-spatial Data Clearinghouse (ASGDC) provides an electronic pathway for the public to access a wide variety of information in the form of maps, images and descriptions about Alaska geo-spatial data. This site is developed as a "node" on the growing framework of public sites across the nation which together constitute the electronic back-bone of the National Spatial Data Infrastructure.

About the Alaska DNR

The Department of Natural Resources manages all state-owned land, water and natural resources, except for fish and game, on behalf of the people of Alaska. When all land conveyances from the federal government are completed, the people of the state will own land and resources on 104 million acres: Approximately 90 million acres have been conveyed so far. The state owns approximately 65 million acres of tidelands, shorelands, and submerged lands and manages 34,000 miles of coastline. The state also owns the freshwater resources of the state, a resource that equals about 40% of the entire nation's fresh water.
