The WSDOT GeoData Distribution Catalog, maintained by the Office of Information Technology, is a centralized distribution site for geographic information system data produced at the Washington State Department of Transportation.
Data provided here is used by WSDOT's transportation partners, government entities, schools, private businesses, and the general public. The WSDOT GIS Community actively promotes inter agency data exchange and resource sharing; therefore, data on this site is available for download free-of-charge.
Our data is provided in ESRI shapefile, georeferenced .jpg, and Mr. SID formats. See the sidebar to the left for more details. If you do not have a GIS solution to view this data, you can download free of charge open source software for Windows, Macintosh, or Linux from Quantum GIS (Qgis). Many of the datasets listed below are also available for viewing in the WSDOT Online Map Center.
