Question

Which atmospheric correction method is most useful for easy detection of haze from the images and why?
(a.) Spectral Information based correction; AOT bands can easily be obtained
(b.) Temporal Information based correction; comparison between multi-temporal images
(c.) Angular Information based correction; Multiple angles of observation
(d.) Spatial Information based correction; spatial matching of clear and hazy regions of an image

Answer 1

Answer:

Spatial "information based correction": "spatial matching of clear and hazy regions of an image" is method used for detection of haze from the images.

Option (d).

Explanation:

The "fineness of visible detail" can be seen using spatial resolution by  "high and low resolutions". Spatial resolution is affected by factors like smoke, haze, blurred particles and clouds.

Haze, mist, storms and pollution is detected via "spatial resolution at approximately, 0.52 – 0.72 µm" of a visible wavelength range. The spatial resolution is determined by the sensor’s altitude, the "field of view" and viewing angle. Hence, spatial information based correction is the most useful method.
