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 captures natural energy, like sunlight, while active remote sensing emits its own energy to measure reflected signals.

Can you give examples of each type?

Sure! An example of passive remote sensing is a satellite that captures images of the Earth using sunlight. An example of active remote sensing is a radar system that sends out radio waves and measures the time it takes for them to return.

What are some applications of remote sensing?

Remote sensing is used in various fields such as agriculture for crop monitoring, environmental science for land use analysis, and disaster management for assessing damage after events like hurricanes.

How does remote sensing benefit environmental monitoring?

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