9. CASI at GEZIRAT SIYUL Reef, Red Sea Results of 4SM modeling 4SM: the Self-calibrated Supervised Spectral Shallow-sea Modeler

10. CASI at GEZIRAT SIYUL Reef, Red Sea Image_HER: RGB CC Image_HED: RGB CC Image_HEB: RGB CC raw data cleaned data spectral bottom reflectance

11. CASI at GEZIRAT SIYUL Reef, Red Sea Image_Z: depth Image_B: average Image_BSC: classified in decimeters bottom reflectance bottom signatures

12. CASI at GEZIRAT SIYUL Reef, Red Sea Image_wZ This shows the extent of areas where modeling is based * on the red band at 608 nm (red), * or on green bands (shades of green). Bright blue is where red band is saturated. Black is where a null depth is computed. Purple is for optically deep waters. Light blue is for areas of NoData. There is clearly a lack of red bands.

22. The original pixel resolution is 1 meter but the previous images are reduced to 10% of their normal size (i.e. a 10 m pixel resolution.) CASI data collected in the Red Sea for Dr Chip FLETCHER SOEST, U. of Hawaii (www.soest.hawaii.edu) aerial photographs from J. Harney’s home page and provided for 4SM processing by Hyperspectral Data International (www.hdi.ns.ca)
