Earth observation sounds like a single activity until you ask what the satellite is actually measuring. A camera, a radar instrument, an infrared sensor, and a microwave radiometer can all look at the same coastline and return different truths. One may show a cloudless picture of farms and roads. Another may see through cloud and darkness to map floodwater or surface texture. Another may show heat, fire behavior, sea surface patterns, or the thermal character of a city after sunset.
