Describe remote sensing technique.
✓
Answer
A remote sensing method is a method of obtaining a device with the help of a remote device without having direct physical contact with any object or event.
In $1960,$ a geographer named Evelyn Pratt first used the term remote sensing.
The beginning of the process of this method can be traced back to the origin of the organism, if our five senses need any other senses.
All the senses that feel the sensation reach the brain.
Your brain is a kind of processor that organizes the information of all the senses and determines its end result.
Thus, each sense is a sensor.
This is the basic concept of today's remote sensing technique and is intended to get information about the earth.
Ancient and modern travelogues, pictures, photos, maps, films, etc. provide information about the earth.
It now takes aerial photos and satellite images, called satellite imagery.
In the remote sensing technique, photos taken from planes and satellites are based on imagery.
Aerial photos are images taken of the Earth's surface by a camera mounted on a balloon or aircraft.
Remote sensing satellites have two types of orbits.
