Question

What is remote sensing?

Answer 1

1. Remote sensing is the process of gathering information about an object, location, or phenomenon without physically contacting it.
2. Typically, satellites, drones, or aircraft fitted with sensors acquire data from the Earth's surface in the form of photographs, radiation, or other signals.
3. This data is then analysed to track changes, specific situations, or long-term trends.
4. Remote sensing may collect data at a variety of wavelengths, including visible light, infrared, and microwave radiation.
