Consider the following statements regarding the Remote Sensing Survey: 1) Information transfer is accomplished by the use of electromagnetic radiation 2) Remote Sensing from space is done by satellites 3) Remote Sensing has no application in Earthquake prediction Which of the above statements are correct? Correct Answer 1 and 2 only
Remote sensing survey:
It is the art and science of obtaining information about an object or feature without physically coming in contact with that object.
Characteristics of remote sensing
- The data collected using it is in various forms such as variations in acoustic wave distributions (SONAR), variations in force distributions (gravity meter), variations in electromagnetic energy distributions.
- The remote sensing is the process of inferring surface parameters from measurements of the electromagnetic radiation (EMR) from the Earth’s surface.
- In space-borne remote sensing, sensors are mounted on a satellite orbiting the earth.
Advantages of remote sensing are:
- Remote sensing provides data on large areas.
- It can be used to obtain data of very remote and inaccessible regions.
- With the help of remote sensing imagery of any area over a continuous period through which any natural changes in the landscape (earthquake) can be analyzed.
- It is relatively cheap when compared to employing a team of surveyors.
- Easy and rapid collection of data.
- Rapid production of maps for interpretation.
