How to see the resolution of satellite images?

The practice of aerial photogrammetry can be used as a reference for the reference and analysis of satellite images and the selection of drawing scale. This is because their mapping principles are similar, and aerial photogrammetry has a lot of practical experience and experimental data. It is a very mature choice of satellite image resolution, which not only considers the requirements of different scale surveying and mapping for image resolution, but also considers the specifications of available satellite image products, because satellite photography is different from aerial photography, and its photography height (that is, photography scale) is fixed. .
