Question:medium

IRS LISS - III Satellite sensor resolution and number of bands respectively are

Show Hint

The IRS (Indian Remote Sensing) LISS-III sensor is a multispectral imaging instrument, so it is described by both its ground spatial resolution and the number of spectral bands it records.

  • 23.00 m × 23.00 m and 1
  • 5.80 m × 5.80 m and 4
  • 23.00 m × 23.00 m and 4
  • 5.80 m × 5.80 m and 1
Show Solution

The Correct Option is C

Solution and Explanation

Step 1: Identify the sensor.
The IRS LISS-III is an Indian Remote Sensing multispectral sensor, so it is described by both its ground resolution and how many spectral bands it has.

Step 2: Recall its spatial resolution.
The LISS-III has a ground cell size of about 23.5 m, which is commonly written as 23.00 m by 23.00 m.

Step 3: Recall its number of bands.
Being multispectral, it records in 4 bands, namely green, red, near infrared and short wave infrared.

Step 4: Compare with the options.
The 5.80 m options describe the LISS-IV / panchromatic type sensors, not LISS-III, so they are ruled out.

Step 5: Pick the matching pair.
The pair 23.00 m by 23.00 m with 4 bands matches LISS-III.

Step 6: State the answer.
The resolution and bands are 23.00 m by 23.00 m and 4.
\[ \boxed{23.00 \text{ m} \times 23.00 \text{ m and } 4} \]
