The Survey Unit is responsible for all survey services needed for transportation projects, while developing and following standards, specifications, and guidelines. These services include; route surveying, geodetic surveying, construction surveying, boundary surveying, LiDAR, bathymetric, and other special survey services that are needed within the Agency. The spatial data collected provides the basic framework used to map, build, and maintain Vermont’s transportation system. The Survey Unit manages the Continuously Operating Reference Station (CORS) program that provides State Plane Coordinates and Datum Elevations for Agency projects.

Visit the Geodetic Survey or Route Survey pages for more information.

We make our Survey and Right of Way data available in a GIS format through the Right of Way Spatial Data Hub. The ROW Data Hub also includes up to date parcel information, roadway asset data (bridges, culverts, etc.), and maps our roadway centerlines. For questions about the ROW Data Hub, please contact
