Question

What are the advantages and disadvantages of Remote Sensing?

Answer 1

a. Advantages of Remote sensing:

1. It is the only practical way to obtain data from inaccessible regions, e.g. Antarctica, Amazon forest.
2. It helps in constructing cheap base maps in the absence of detailed land surveys.
3. It detects the spread of natural calamities such as floods, forest fires, and volcanic eruptions so that immediate rescue operations and planning can be carried out.

b. Disadvantages of Remote sensing:

1. It is difficult to prepare large-scale maps from obtained satellite data.
2. The technique is very expensive for small areas requiring one-time analysis.
