Answer:
Explanation:
Advantages of remote sensing technology:
1. Large area coverage: Remote sensing allows coverage of very large areas which enables regional surveys on a variety of themes and identification of extremely large features.
2. Remote sensing allows repetitive coverage which comes in handy when collecting data on dynamic themes such as water, agricultural fields and so on.
3. Remote sensing allows for easy collection of data over a variety of scales and resolutions.
4. A single image captured through remote sensing can be analyzed and interpreted for use in various applications and purposes. There is no limitation on the extent of information that can be gathered from a single remotely sensed image.
5. Remotely sensed data can easily be processed and analyzed fast using a computer and the data utilized for various purposes.
Disadvantages of remote sensing:
1. Remote sensing is a fairly expensive method of analysis especially when measuring or analyzing smaller areas.
2. Remote sensing requires a special kind of training to analyze the images. It is therefore expensive in the long run to use remote sensing technology since extra training must be accorded to the users of the technology.
3. It is expensive to analyze repetitive photographs if there is need to analyze different aspects of the photography features.
4. It is humans who select what sensor needs to be used to collect the data, specify the resolution of the data and calibration of the sensor, select the platform that will carry the sensor and determine when the data will be collected. Because of this, it is easier to introduce human error in this kind of analysis.
5. Powerful active remote sensing systems such as radars that emit their own electromagnetic radiation
