What is the major limitation of aerial photography compared to satellite remote sensing?
A. Higher resolution
B. Limited area coverage
C. Dependence on daylight and weather conditions
D. Expensive data acquisition
Answer: Option C
Solution (By Examveda Team)
Aerial photography requires clear weather and daylight.Satellite sensors (like radar) can operate in all weather and lighting, overcoming this limitation.This Question Belongs to Geological Engineering >> Remote Sensing And GIS In Geological Engineering
