Black & white aerial photo



Just as infrared aerial photos, black and white photos serve as an alternative perspective of geographic areas. They are especially useful in highlighting areas of visible light contrast and thus serve as good references for areas with distinct shapes such as buildings, roadways, and mountains. The black and white aerial photo shown here defines a municipal area mapped by the USGS. The buildings are very sharp in this photo and easy to differentiate from the surrounding landscape.
