What is 'orthorectification' in remote sensing imagery processing?
A. Correcting atmospheric distortions
B. Removing cloud cover
C. Correcting geometric distortions due to terrain and sensor tilt
D. Enhancing color contrast
Answer: Option C
Solution (By Examveda Team)
Orthorectification removes distortions caused by terrain relief and sensor angles.It produces accurate, planimetrically correct images useful for mapping.This Question Belongs to Geological Engineering >> Remote Sensing And GIS In Geological Engineering
