Any object, point, etc., toward which some­thing is directed. An object which reflects a sufficient amount of a radiated SIGNAL to produce an echo signal on detection equipment. See RADAR TARGET, SONAR TARGET. The distinctive marking or instrumentation of a ground point to aid in its iden­tification on a PHOTOGRAPH. In PHOTOGRAMMETRY, target designates a material marking so arranged and placed on the GROUND as to form a distinc­tive pattern over a geodetic or other control point marker, on a property corner or line, or at the positi­on of an identifying point above an underground facili­ty or feature. A target is also the image pat­tern on AERIAL PHOTOGRAPHS of the actual MARK placed on the GROUND prior to PHOTOGRAPHY.
