Sanborn Contour Maps products are mapping datasets that display highly accurate contour lines showing equal elevation that correspond to the orthometric heights of the bare earth surface. The contour lines and contour intervals depict elevation / altitude and depth, illustrating the general terrain for an area. Improvements in aerial data acquisition and production methodologies have increased the accuracy of current topographic maps, while helping to reduce the time needed to create them. To develop topo maps, aerial data acquisition is used primarily (supplemented by ground survey where necessary) as larger areas can be mapped more efficiently than through conventional survey methods.
