The Transportation Data & GIS Office produces map products that are used by Federal, State and Local Government Agencies as well as the general public.
Maps For Printing: 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 is compatible with Bentley's Microstation software. WSDOT has a large selection of files located on our FTP site for you to browse through as well as a Quad Map Index for those who need quadrangle files in .dgn format.
The milepost maps display mileposts along the state highway system at 10 mile intervals (5 mile intervals for the Puget Sound enlargement) as well as mileposts at the junctions of state highways, along with county and region boundaries, to the nearest one hundredth of a mile.
The state base map shows the state highway system, county boundaries and selected communities in two different sizes. The Puget Sound enlargement base map shows the state highway system, county boundaries and selected communities in two different sizes, but at a larger scale than the statewide map. The simple design allows for other highway information to be drawn on the map.
The WSDOT region maps are designed in color as quick reference maps. They are perfect for PowerPoint presentations or can be inserted into documents. They are available in .pdf format for print jobs and .jpg format for digital projects. One map shows WSDOT regions and county boundaries and the other shows WSDOT regions and selected state highways.
The State Wall Map is a single-sheet map which includes all of Washington State, selected road information, geographical features and political boundaries.
Freight and Goods (FGTS) Maps : Freight and Goods Transportation System (FGTS) maps are provided to display tonnage volume classifications on county roads, city streets, and state highways. The state and Puget Sound maps show a generalized view and the county, urbanized area, and town (rural city) maps show more detail.
