The first two projects are for the North Carolina Department of Transportation. Re-selected by the DOT for its annual statewide mapping initiative, Sanborn will provide professional photogrammetric mapping services for the entire state, which encompasses 52,669 square miles. The DOT will use the data to aid highway design, which includes road improvements and the development of new routes for the state, which is the 11th most populous in the U.S.
In a separate contract, Sanborn will provide helicopter and airborne GPS/Inertial Navigation System (INS) aerial photography services and high accuracy profile mapping for NCDOT. The AGPS/INS photography will be used to develop design-scale digital mapping and digital orthophoto imagery. The low altitude helicopter photography will be used to develop high accuracy road profiles data conforming to survey grade accuracy standards. The information Sanborn provides will help the NCDOT in its efforts to develop a more integrated, multimodal transportation system to meet the demands of the 21st century. Sanborn has earned NCDOT’s highest-ranked subcontractor status for the last three years.
Additionally, Sanborn was hired by Whitfield County, Georgia, to provide countywide black-and-white digital orthophotos and GIS services for the 290-square mile county. Whitfield County’s GIS and tax departments will use the ½-foot pixel resolution orthophoto images for a variety of purposes. Sanborn will acquire the AGPS/INS aerial photography during the 2003 spring flying season and complete the project in the fall of 2004.
The City of Lakewood, California, hired Sanborn to provide 1"=100' scale, color digital orthophoto imagery with a ¼-foot pixel resolution for the city. Sanborn will fly the 12-square-mile area in the spring of 2003 and complete the project in July. The city’s tax, planning and public works departments will use the data to better serve Lakewood’s 74,000 residents.
