What is Aerial Photogrammetry

Aerial photogrammetry is the science of obtaining accurate geometric measurements using photographs taken from an aerial platform. It includes aerotriangulation, or block adjustment of multiple photographs using point of common detail normally derived from Real Time Kinematic (RTK) satellite navigation and airborne Global Positioning System (GPS).
