GIS Applications

Ecology uses geographic information system (GIS) tools and procedures as aids in accomplishing its mission of protecting the land, air, and waters of the state. The agency has built and maintains the GIS applications described here in order to help our staff and others understand the diverse natural and cultural environment we live and work in. As a public service, we are making our GIS applications available here.
