Question

What is mean by remote sensing....

Answer 1

Answer:

The advantages of remote sensing include the ability to collect information over large spatial areas; to characterize natural features or physical objects on the ground; to observe surface areas and objects on a systematic basis and monitor their changes over time; and the ability to integrate this data with other ..

There are two types of remote sensing technology, active and passive remote sensing. Active sensors emit energy in order to scan objects and areas whereupon a sensor then detects and measures the radiation that is reflected or backscattered from the target.

Answer 2

Answer:

Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance (typically from satellite or aircraft). ... Cameras on satellites can be used to make images of temperature changes in the oceans.
