What is remote sensing?

Remote sensing is gathering information about objects or areas from a distance using sensors mounted on aircraft or satellites. It lets us observe large areas and track changes over time by measuring energy that is reflected or emitted from the surface in different wavelengths, which helps identify features like land cover, vegetation health, and mineral deposits. The best choice reflects this broad capability: it uses data from satellites or aircraft to monitor land, forests, or minerals. Ground-based surveys require being on site, so they aren’t remote sensing. Excluding satellite data or focusing only on ocean data misses the full scope of remote sensing, which applies to land, forests, minerals, and more, using both aerial and satellite platforms.
