Photogrammetry is the science of creating measurements from aerial imagery, especially for plotting the exact positions of surface features. Its use is as old as photography itself. It is used in topographic mapping to assist in showing natural and manmade features, as well as in many other fields, such as meteorology, for determining the actual wind speed of a tornado. 

Photogrammetry can make it easier to understand the 3-D features of a geographic area, integrate descriptive data, and use spatial analysis tools to support analysis and interpretation of data.
