What Is Aerial Mapping:

Aerial mapping is more efficient then traditional methods when surveying large tracts of land. A stereoscopic image of the land is taken from a series of aerial photography to create an accurate photographic model or digital terrain model which is than used for a variety of surveying and engineering purposes. Surveyors are needed to provide horizontal and vertical control for the mapping process and to locate supplemental information like fire hydrants, manholes, or other information not visble in the photographs. Under the direction of the aerial mapper, the surveyor places large targets on the ground for the aerial photography. The surveyor provides the aerial mapper with XYZ coordinates of the targets to be used as the control points for the aerial photography and any supplemental information. In critical areas, the surveyor is capable of providing information that is more precise than the aerial mapping.

In addition to providing an efficient means for a developer to survey a large development, aerial photography is becoming relevant in the implementation of municipal GIS Systems. Aerial photography, satellite data, and radar imagery in our day to day process of spatial information, and as these new technologies become more widespread, surveyors are needed to provide a physical reference between the data and our physical world.
