A. Requires large storage space
B. Limited ability to represent continuous data
C. Difficult to overlay
D. Does not support attribute data
Answer: Option A
Solution (By Examveda Team)
Raster datasets often require significant storage due to high pixel counts.However, they excel at representing continuous data and support overlay operations.This Question Belongs to Geological Engineering >> Remote Sensing And GIS In Geological Engineering
