Welcome! Ecology's GIS staff builds and maintains spatial datasets and applications, conducts GIS projects, and publishes GIS maps in support of the agency's mission of protecting the land, air, and waters of the state. Tools used in this work include GIS software by Environmental Systems Research Institute (ESRI) including ArcInfo, ArcView, ArcSDE, ArcGIS Server, and ArcIMS.
These pages are targeted for an audience experienced with GIS terminology and standards. If you are new to GIS, you can learn more at http://erg.usgs.gov/isb/pubs/gis_poster/ (USGS) or http://www.gis.com (ESRI). Also, our Frequently Asked Questions (FAQ) page may help you with our data and maps.
