There are many types of satellites used for remote sensing of the Earth. The three major types are meteorological, oceanographic, and terrestrial satellites. Meteorological satellites are used to obtain information about the Earth's weather. The data obtained from these satellites are entered into a computer to create a forecast model. Oceanographic satellites obtain data about the Earth's oceans and other water bodies to help us understand the oceanic system of tides, water temperatures, etc.
Terrestrial satellites obtain data about the Earth's land surface.
The range of the electromagnetic spectrum allows researchers to see the Earth from a different perspective. These data are useful in predicting crop yields for agriculture and aiding cartographers in map making. The extent of the use of these satellite systems is limitless.
