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 survey
- DAll of the aboveCorrect
Solution
Concept
Advantages of remote sensing in land use
Formula
NONE
Step-by-step solution
1. Remote sensing sensors acquire high-resolution imagery covering large spatial extents rapidly. 2. Satellite and aerial remote sensing can observe remote or inaccessible terrain without physical ground access. 3. Rapid coverage over extensive areas significantly lowers overall survey time and costs relative to ground surveys. Answer: D
Explanation
Remote sensing allows rapid acquisition of images across expansive geographical areas without requiring physical ground access. It overcomes physical terrain obstacles and significantly reduces surveying costs compared to traditional ground methods. Therefore, all the listed factors contribute to its widespread application in land use analysis.
Why the other options are wrong
A) Rapid acquisition of large area images is only one of several reasons remote sensing is used. B) Eliminating access problems is only one advantage of remote sensing. C) Lower cost relative to ground survey is only one benefit of remote sensing.
Shortcut
Remote sensing offers speed, remote access, and lower cost, making "All of the above" correct.
Common mistake
Selecting the first plausible reason without reading all options to notice 'All of the above'.
Correct answer: D) All of the above
