8. describe four different processing techniques that can be applied to landsat satellite images.

Enhancement, Image pre-processing,  Classification, Transformation

Explanation:

TECHNIQUE USED IN LANDSAT SATELLITE IMAGE ARE

1. Enhancement :-

It can be used to perceive visually. The picture that has already been corrected is enhanced to be interpreted

2.Image pre-processing :-

Used in the correction process. It help to  corrects the radiometric, geometric and atmospheric distortion.

3. Classification :-

 Used to strengthen the picture by condensing the pixels.

4. Transformation :-

Used to define characteristics such as geological constructions, models of drainage structure, bridge, highway, houses, etc.
