Satellite data, also referred to as satellite imagery, provides information about Earth and other planets in space, which are collected by man-made satellites in their orbits. Satellite data allow us to observe the Earth, as satellites deliver information about the surface and weather changes on the planet Earth.
Satellite data is generated via remote sensing technologies. In fact, it is very useful for providing authentic information about the atmospheres, oceans and land masses by constantly collecting data from joined satellites.
