The GIS & Roadway Data Office produces map products that are used by Federal, State and Local Government Agencies as well as the general public.
Maps: Our cartographic products provide a selection of printable maps of Washington State that are available for download in Adobe PDF format.
Map Applications: These provide a dynamic way to view and use WSDOT data by using just your web browser.
GIS Data: The geospatial data comes in several different file formats and depending on the data and the software you use, will determine what files you'll need. The GeoData Catalog is the source of these files and the formats are compatible with ESRI's ArcGIS software.
CADD Data: The .dgn files were digitized from the USGS topographic quadrangle maps. Each CADD file represents a 30 x 60 minute quadrangle at a scale of 1:24,000 and are compatible with Bentley's Microstation software.
All the data on this site is available for download, free-of-charge. If you do not see what you're looking for or have a questions regarding the products listed here, please contact The GIS & Roadway Data Office at 360-596-8921.
