Remote Sensing is the scanning of the earth by satellite or high-flying aircraft in order to obtain information about it. Remote sensing is also about technology that remotely gathers data (such as the UFO Drone that flies by sensing data). https://amzn.to/3c0Zbng
Remote Sensing goes beyond recording photo and video images visible to the human eye. Both optical and radar satellites provide multispectral images for comprehensive spatial analysis with multiple band combinations and color transformations. Viewable spectra comprise microwave, NIR, IR, TIR, as well as other methods.
The major types of remote sensing include active or passive devices that either have their source of illumination or rely on solar energy and reflectance or emittance properties of the target.
What is more important, GIS technologies enable to correlate spatial data with geographic maps, thus monitoring the required area, be it a city, forest, mountain, water object, or farmland.
