4-5 Specifications for Airborne Acquisition. Maps must be provided to the con-
tractor of the image acquisition area. They must be in the projection and datum required,
for example Geographic and WGS84. The collection flight lines should be drawn on the
maps with starting and ending coordinates for each straight-line segment. If an area is to
be imaged, then the overlap between flight lines must be specified, usually 20%. If the
collection technique is that of overlapping frames, then both the sidelap and endlap must
be specified, between 20 and 30%.
