Two short definitions of Remote Sensing might be presented as follows: “To study or measure an object without being in physical contact with it” or “feeling without touching”. As defined above, the term generally implies that the sensor is placed at some considerable distance from the sensed target, in contrast to close-in measurements made by "proximate sensing." sometimes given as "in situ" sensing. Remote sensing means aerial photography too. Aerial platforms are primarily stable wing aircraft. Aircraft are often used to collect very detailed images and facilitate the collection of data over virtually any portion of the Earth's surface at any time. The scale and quality of the data collected is affected by several factors including, but not limited to, altitude of the aircraft, position of the plane, and the quality of the photographic equipment used.
