Remote Sensing | NASA Earthdata
Remote sensing is the acquiring of information from a distance. NASA observes Earth and other planetary bodies via remote instruments on space-based platforms (e.g., satellites or spacecraft) and on aircraft that detect and record reflected or emitted energy.
Remote sensing - Wikipedia
Remote sensing makes it possible to collect data of dangerous or inaccessible areas. Remote sensing applications include monitoring deforestation in areas such as the Amazon Basin, glacial features in Arctic and Antarctic regions, and depth sounding of coastal and ocean depths.
Remote sensing is obtaining information about an object from a distance. Photography is a very common form of remote sensing. There are different ways to collect data, and different sensors are used depending on the application. Some methods collect ground-based data, others airborne or spaceborne. What information do you need? How much detail?
What is remote sensing and what is it used for?
Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). Special cameras collect remotely sensed images, which help researchers "sense" things about the Earth. Some examples are:
