The difference between aerial photogrammetry and space photogrammetry

The biggest difference between aerial photos and satellite photos is the difference of imaging platform. As the name implies, aerial photographs are generally taken by airplanes, and the imaging height is generally several kilometers to ten thousand meters. The smaller the width, the higher the height and the lower the resolution. Due to the unstable flight attitude of the aircraft, aerial photos are generally distorted. Satellite images are taken by satellite platform, and the height is more than several hundred kilometers. Today, high-resolution satellites can reach 0. 1-0.5 meters. The platform is stable, slightly deformed and wide relative to the aircraft.

With reference to this, aviation gets aerial photos and aerospace gets satellite photos.
