What does a photographer do?

Generally, it is done by earth observation satellites, which are responsible for taking map images of earth satellites. In fact, the image taken by the satellite in orbit is the satellite remote sensing image. The so-called remote sensing is remote sensing. Satellite remote sensing is to detect the reflection of electromagnetic waves and electromagnetic waves emitted by objects on the earth's surface through satellites in space, so as to extract the information of these objects and complete the long-distance identification of objects. The image obtained by converting and identifying these radio wave information is a satellite map.
