●   Remote sensing gathers and analyzes data without direct physical contact.

●   Applied in various fields like geography, hydrology, ecology, and geology

Types of Remote sensing:

●   Active remote sensing uses artificial radiation sources to probe targets.

●   Passive remote sensing relies on solar radiation, observed in multispectral and hyperspectral sensors.
