What are the different types of remote sensing?

What are the different types of remote sensing?

There are two main types of remote sensing: passive and active. Passive remote sensing detects natural energy emitted or reflected by objects, while active remote sensing emits its own energy to scan objects and collect data.

Can you give examples of each type?

Sure! An example of passive remote sensing is a satellite capturing images of the Earth using sunlight. An example of active remote sensing is a radar system that sends out radio waves to measure distances.

What are some applications of remote sensing?

Remote sensing is used in various fields such as agriculture for crop monitoring, environmental studies for land use mapping, and disaster management for assessing damage.

How does remote sensing benefit environmental monitoring?

It allows for large-scale data collection over time, helping to track changes in ecosystems, monitor deforestation, and assess the impacts of climate change.
