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 remote sensing.
Resolution quantifies the detail and precision of remote sensing data.
Step 2: Identify the four primary resolution types.
- D. Spatial resolution: Smallest ground object size detectable, typically pixel dimensions (e.g., 30 meters).
- B. Spectral resolution: Sensor's capability to differentiate narrow wavelength intervals. High spectral resolution sensors distinguish fine electromagnetic spectrum bands.
- A. Temporal resolution: Frequency of sensor revisits to a specific location for data acquisition (e.g., every 16 days).
- E. Radiometric resolution: Sensor's sensitivity to slight energy (radiance) variations, often indicated by data storage bits (e.g., 8-bit, 12-bit).
- C. Scattered resolution: Not a standard remote sensing resolution type.
Step 3: Determine the correct combination.
The four standard remote sensing resolutions are A, B, D, and E.
