Remote sensing is the science of acquiring information about objects or areas from a distance, typically from aircraft or satellites. Key points of remote sensing include: 1) It allows observation and analysis of an area without direct contact, using sensors to measure electromagnetic radiation reflected or emitted from the target. 2) Remote sensing has evolved from early aerial photography to include various imaging technologies using different parts of the electromagnetic spectrum. 3) Common types of remote sensing include optical, thermal, and microwave sensors, each suited to different applications depending on wavelength.
