Label TextPhotogrammetry uses photography to determine the geometric properties of objects. It is used in topographic mapping in order to accurately depict the nature of the terrain. Contour intervals are used to represent relief. This map showing plans for the I-95 bridge over the Thames River at New London was made using aerial photography. It not only conveys the physical features of the landscape but also includes all of the individual buildings. Plans for the new bridge and its entrance and exit ramps would prove highly controversial, since the area surrounding the bridge was densely built up with many homes and businesses. When it was finally completed in 1973, the double-span steel truss bridge would be the longest in the state of Connecticut.
