What is the relationship between the clarity of satellite imaging and other factors?

One reason is the satellite's own sensor.

The second reason is the weather on earth.

You think the satellite is outside the earth, and there are images of clouds, fog, snow and rain on the earth. Just like which camera you use to shoot the scenery, the fog there is definitely not clear.

I don't think it is enough. What you should be asking is the satellite sensor. What you say clearly is actually that the resolution of the image is high and you can see the house clearly, so you speak clearly. We can reach 0.4 meters, but the image of 0.3 meters will be launched soon. At present, the highest resolution in China is 2m.

To put it bluntly, American satellite sensors are very good and leading the world. Shoot the surface of the earth so clearly.

To put it bluntly, the sensor is the camera where you take pictures. The better the camera, the clearer the photos will be. But one is used on the track and the other is used on the hand.
