Matching Remote Sensing Resolutions and Capabilities
This question requires matching four key remote sensing resolutions with their corresponding capabilities.
Analysis of Resolutions
- A. Spatial Resolution: This refers to the smallest ground area that can be resolved by the sensor. It is directly determined by the IV. Size of the pixel. A smaller pixel size indicates higher spatial resolution.
- B. Spectral Resolution: This capability relates to the sensor's ability to distinguish between different wavelengths of electromagnetic radiation. It is defined by the I. Narrowness of the spectral bands. Sensors with narrower spectral bands have higher spectral resolution.
- C. Radiometric Resolution: This describes the sensor's ability to distinguish between different levels of electromagnetic radiation intensity, essentially measuring signal strength. It is associated with the II. Variations in brightness. Higher radiometric resolution means more discrete levels of brightness can be detected.
- D. Temporal Resolution: This refers to the frequency at which a satellite or sensor passes over the same point on Earth's surface. It is defined as the III. Revist capability. A shorter revisit time indicates higher temporal resolution.
Correct Matching
Based on the analysis, the correct matching is:
- A - IV
- B - I
- C - II
- D - III
This corresponds to Option 2.

Choose the correct answer from the options given below :
- Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A): A variety of Remote Sensing methods can be used to detect, monitor and respond to natural disaster as well as to assess disaster vulnerability.
Reason (R): Tonal values are important because they often form distinct image patterns that may be of great significance in image interpretation.
In the light of the above statements, choose the most appropriate answer from the options given below: The operations aim to correct distorted and degraded image data to create a more faithful representation of the original Earth features during disaster is known as:
