What type of map is most useful for assessing landslide hazards using GIS?
A. Topographic map
B. Geological map
C. Slope map derived from DEM
D. Political map
Answer: Option C
Solution (By Examveda Team)
Slope maps show terrain steepness, critical for landslide risk assessment.GIS derives slope from DEM data to identify unstable zones.What is the primary principle behind remote sensing?
