What are the benefits of using satellites for mapping?

Satellites can provide footage of target areas, for example, the site of a construction project when needed. Another reason to use satellite imagery is for multispectral analysis. Multispectral images can capture light at frequencies beyond the visible range, such as infrared.

How do satellites create maps?

The answer is simple: Satellite camera takes two pictures in one time period. The first image is in black and white, and the second image is in color. In those microseconds between shots, the plane managed to fly some distance, so on the satellite map, a copy appeared.
