When was remote sensing first used

Such data have been widely used in natural resources inventory and mapping. Major areas include agriculture, forest, wet land, mineral exploration, mining, etc. A new type of sensor called an imaging spectrometer, has been developed. A more detailed description of this subject can be found in Staenz Proposed EOS aiming at providing data for global change monitoring.

Various sensors have been proposed. Satellite remote sensing can be traced to the early days of the space age both Russian and American programs and actually began as a dual approach to imaging surfaces using several types of sensors from spacecraft.

These rockets, while never attaining orbit, contained automated still or movie cameras that took pictures as the vehicle ascended. Then, with the emergence of the space program in the s, Earth-orbiting cosmonauts and astronauts acted much like tourists by taking photos out the window of their spacecraft. The term "remote sensing," first used in the United States in the s by Ms.

Evelyn Pruitt of the U. The use of remote sensing commonly results in considerable hydrological information at minimal cost. This information can be used to speed-up the development of water resources, to improve management practices, and to monitor environmental problems.
