The Geodetic Survey Branch of the GeoMetrix Office (formerly Geographic Services) is a WSDOT Headquarters office located in Tumwater, Washington. A consistent controlled survey network is essential to credible data. Geodetic Survey maintains a network of very accurately located survey points that make up the starting point for design and construction project work. By working from a standard survey network, WSDOT project work done at different locations and at different times better align with each other where they meet. Features located using GPS are related accurately in relationship to the roadway. By sharing our survey information with others outside the department, our right of way boundaries are more apt to align with local property surveys. Sharing accurate data saves funds, time, and is easy to use across many software platforms.
