Remote Sensing - Components, Types, Working and Applications
2024年2月27日 · Remote sensing is a technology for acquiring information about the earth's surface without actually being in contact with it. This is done by sensing and recording reflection or emitted energy & processing, analyzing, and applying that information.
Remote sensing - Wikipedia
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets.
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?
