Aerial Photography Technical Design Specifications
1 Scope
This document specifies the basic requirements and techniques for aerial photography design (hereinafter referred to as "aerial photography design") in frame-type digital aerial photography.
Requirements, aerial photography design procedures and methods, preparation of aerial photography technical design documents (hereinafter referred to as "aerial photography design documents"), and verification requirements.
This document applies to the technical design of aerial photography using a frame-type digital aerial camera mounted on a manned aircraft.
This should be used as a reference when flying aircraft equipped with other digital aerial cameras or using unmanned aerial vehicles.
