Georgia Department of Transportation Georgia DOT Aerial Photography, Lidar, and Survey Services, Statewide, Georgia

The department also offers administrative support to the State Road and Tollway Authority and the Georgia Rail Passenger Authority. GDOT oversees waterways, including the Intracoastal Waterway, as well as the ports in Savannah and Brunswick. 

With a commitment to facilitating the timely and efficient movement of people and goods across the state, GDOT focuses on maintaining transportation safety and alleviating congestion. The department conducts various projects, including roadway widening, repaving, safety improvements, and rehabilitation work. Designing these projects relies on a solid foundation of accurate mapping, ensuring the success and effectiveness of GDOT’s initiatives in enhancing Georgia’s transportation infrastructure.  

Under our current 5-year Master Services Contract for Aerial Photography, Lidar and Survey Services, GPI Geospatial has successfully completed 75 assignments through 21 work orders. The range of services includes aerial photography, aerial lidar acquisition and processing, mobile lidar scanning, control surveys, field–run topographic surveys, boundary surveys and platting, photogrammetric feature collection, and project report preparations. In addition to planned projects, GPI Geospatial demonstrates agility by quickly responding to emergency projects to capture data for issues like rock slides or slope failure sites. Typical projects include ground control and aerial data collection to achieve an accuracy of 0.10′ on paved surfaces. Lidar collections maintain a minimum point density of 30–40 points per meter or higher in a single pass. Field-collected information on topography, drainage, utility, right-of-way, and property details supplement the aerial mapping as required.
