GIS Data

Ecology maintains the spatial datasets described here in order to better describe the diverse natural and cultural environment that we live and work in. As a public service, we have made some of our data available for viewing and downloading here.

Ecology's Spatial Datasets

Our spatial datasets are available as shapefiles (zipped), our metadata files are in FGDC format, and our view files are in GIF format. Our standard projection and datum for our shapefiles is Washington State Plane, South Zone, NAD 83 HARN, units feet, unless otherwise noted. If you are using NAD 27 and want to reproject our data to that standard, see our FAQ question. (More information on our data standards.)

If you can't find the data that you are seeking here, please check our links to other websites at the bottom of this page. Please use our Digital Data Request Form (view HTML format) to order data (if you are unable to download it here).

We also have maps available. For a listing of these maps, please go to our GIS Maps page.

Having problems using our data? Our Frequently Asked Questions (FAQ) and Help page may have the answer.

GIS DATA CONDITIONS OF USE

Please note that our GIS data, while available for free of charge, is covered by Ecology's Conditions of Use Statement. Please view the conditions on the Site Information Page http://www.ecy.wa.gov/siteinfo.html.
