[kən¦trōld mō′zā·ik] (graphic arts) An assemblage of aerial photographs in which various adjustments have been made to improve accuracy and correct for distortions.

controlled mosaic

A mosaic in which the distance and the directions are accurate. A controlled mosaic is obtained when the photographs are carefully assembled so that horizontal control points agree with their previous plotted positions. Each air photo is corrected for aircraft height and tilt variations. The central portions of air photos are cut out and aligned with adjacent air photos. Each photo is further oriented by matching features with survey control points for the area. A controlled mosaic is the basic requirement to permit accurate targeting.
