The system that uses the Sun as a source of electromagnetic energy and records the naturally radiated and reflected energy from the objects is called

1. Geographical Information System
2. Global Positioning System
3. Passive Remote Sensing
4. Active Remote Sensing

Correct answer: Passive Remote Sensing

Solution

Passive Remote Sensing relies on the natural energy emitted or reflected by objects, primarily from the Sun, to gather data, making it distinct from Active Remote Sensing, which uses its own energy source.
