Characteristics of remote sensing data & pre-processing. 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.
