Remote sensing is being used in land use analysis because
- AImages of large areas can be acquired rapidly
- BProblem of access is eliminated
- CIt is cheaper as compared to the ground surveys
- DAll of the aboveCorrect
Solution
Concept
Advantages of remote sensing in land use
Formula
NONE
Step-by-step solution
1. Remote sensing provides synoptic coverage, enabling rapid acquisition of imagery over large geographical areas. 2. Satellite or aerial sensors can map inaccessible or remote terrains without requiring physical ground presence. 3. Collecting spatial data via remote sensing significantly reduces overall time and cost relative to traditional ground surveys. 4. Hence, all listed reasons justify the use of remote sensing in land use analysis. Answer: D
Explanation
Remote sensing allows rapid coverage of vast geographical areas and provides data for inaccessible or hazardous terrains without requiring physical ground presence. Additionally, it significantly reduces the overall time and operational costs compared to traditional land surveys, making all the options correct.
Why the other options are wrong
A) Option A is a key advantage but not the sole reason for using remote sensing. B) Option B is a valid benefit but does not represent all advantages on its own. C) Option C is a major cost benefit but only forms part of the full reasoning provided in option D.
Shortcut
Remote sensing gives rapid coverage, removes access barriers, and saves costs (All of the above).
Common mistake
Selecting a single specific advantage of remote sensing instead of recognizing all listed benefits.
Correct answer: D) All of the above
