Which type of Remote sensing represents the single band of visible spectrum to produce black and white images?

AHyper-spectral

BMulti-spectral

CThermal spectral

DPanchromatic

Answer:

D. Panchromatic

Read Explanation:

  • Panchromatic -Captures the entire visible spectrum in a single band, resulting in high-resolution grayscale (black and white) imagery.

  • Multi-spectral: Uses several broad bands (e.g., Red, Green, Blue, Near-Infrared).

  • Hyper-spectral: Uses hundreds of very narrow, contiguous bands.

  • Thermal spectral: Detects heat (long-wave infrared radiation) rather than visible light.
