Geological Survey, 511 National Center, Reston, VA 22092 ABSTRACT: Since the mid-1960s, a variety of remote sensing systems have been launched for imaging the Earth, moon, and other planets. Remote Sensing is a technology to gather information and analyzing an object or phenomenon without making any physical contact. This technology is used in numerous fields like geography, hydrology, ecology, oceanography, glaciology, geology. A geographic information system is a tool that is used for mapping and analyzing feature events on Earth.
