Question

Remote sensing data have the following type of resolutions:
A. Temporal resolution
B. Spectral resolution
C. Scattered resolution
D. Spatial resolution
E. Radiometric resolution
Choose the correct answer from the options given below:

• A. B, C, D and E only
• B. A, B, D and E only
• C. A, C, D and E only
• D. A, B, C and E only

Hint:

Remember the four "R's" of resolution: 1. Spatial: How small? (Size) 2. Spectral: What colors? (Wavelength) 3. Temporal: How often? (Time) 4. Radiometric: How many shades? (Intensity)

Answer 1

The Correct Option is B

Step 1: Define resolution in the context of remote sensing.
Resolution describes the level of detail and precision of the data captured by a remote sensing system.
Step 2: Identify the four standard types of resolution.
- D. Spatial resolution: Refers to the size of the smallest object that can be resolved on the ground, often expressed as the pixel size (e.g., 30 meters).
- B. Spectral resolution: Describes the ability of a sensor to define fine wavelength intervals. A high spectral resolution sensor can distinguish between very narrow bands of the electromagnetic spectrum.
- A. Temporal resolution: Refers to the frequency with which a sensor can revisit and capture data for the same location (e.g., every 16 days).
- E. Radiometric resolution: Describes the sensor's ability to discriminate very slight differences in energy (radiance). It is often expressed as the number of bits used to store the data (e.g., 8-bit, 12-bit).
- C. Scattered resolution: This is not a standard type of resolution in remote sensing.
Step 3: Conclude the correct combination.
A, B, D, and E are the four universally recognized types of resolution in remote sensing.
