Application of space photogrammetry

Application of space photogrammetry: Space photogrammetry is remote sensing, which is widely used in resource investigation, environmental protection, disaster monitoring, agriculture, forestry, meteorology, geological survey, small-scale topographic mapping, military investigation and other fields.

Space photography is a technology to obtain image data and related data of the earth or other stars by using cameras or other remote sensing detectors in space flight. Although it is customary to use the word "photography" here, it not only refers to the way in which electromagnetic radiation directly acts on negative emulsion to form images, but also includes other ways to obtain information. Space photography usually adopts panoramic photography, multispectral photography and charge-coupled devices? (CCD) array scanning photoelectric imaging and radar scanning imaging. Space photography is the expansion and development of aerial photography.
