  • Subject:General Geography, Earth & Environmental Science

Remote sensing in geography is recognized as the technology of acquiring geographically referable information on the land, ocean, and atmosphere without having physical contact with the object under study. A wide range of sensors for acquiring the data about Earth and its environment are in use in remote sensing. Sensors are required to be fixed in a stable platform for recording, storing, and transmitting the data into ground-based receiving stations.

Platforms

In remote sensing, the vehicle or structure that carried a sensor is called a platform (Table 1; Figure 1). Airborne or space-borne platforms are often used in remote sensing of the environment. Aircraft or balloons are some examples of airborne platforms, while satellites or space shuttles can be considered as space-borne. Balloons, considered to be the ...
