1 Answer

Answer :

Advantages of remote sensing:

1. Relatively cheap and rapid method of acquiring up-to-date information over a large geographical area.

2. It is the only practical way to obtain data from inaccessible regions.

3. At small scales, regional phenomena which are invisible from the ground are clearly visible.

4. Cheap and rapid method of constructing base maps in the absence of detailed land surveys.

5. Easy to manipulate with the computer and combine with other geographic cover ages in the GIS.

6. It is the only way to obtain unbiased data with repetitive coverage.

Limitations of remote sensing :

1. Too costly to build and operate.

2. Needs sound knowledge and understanding of how the instrument is making the measurements.

3. Also requires knowledge of phenomena you are sampling.

4. Thus one can say that data interpretation is difficult.
