REMOTE SENSING
Remote sensing is an art or science by which information about an object can be gathered from a distance without being in physical contact with it .
GLOBAL POSITIONING SYSTEM (GPS)
The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defense.
Points:
No. of satellite = 24(30 in total, 6 in reserve)
Height= 20,500Kms
Software Used= Terra sync
Requirement for Calibration= 4 satellite at a time
Minimum receivers required= 2 to 3
One part of GPS is called Base while other one is called Rover
Range= 30 to 40 Kms
IMAGE PROCESSING SYSTEM (IPS)
IMAGE=Image is collection of pixel.
Each pixel has a DN (Digital No.)
Remote sensing images are recorded in digital form and then
processed by computer to produce images for interpretation purpose.
These images contain large amount of data.
Application of Remote sensing :-
Remote Sensing has applications in following fields:-
Agriculture
Land use & land cover
Geology & geomorphology
Land degradation studies, salt affected area, erosion
Soil conservation planning
Water resources
Forest & mapping
Urban planning
monitoring & change detection
