![]() TCC raw linear enhancement Hamelin Pool is located at the SE of Shark Bay in western Australia | ![]() TCC deglinted histeq enhancement |
![]() Blue band deglinted * There is abundant negative bottom contrast in band ETM_1 * Not easy to settle for a Lswblue value | ![]() Green band deglinted * A body of turbid waters is seen pouring out of SharkBay * Red band deglinted bottom detection is only observed in a ~300 m wide strip along the water line: the bottom of Hamelin Pool shows no bottom detection in the Red band |
![]() computed depth Z |
Final Z= CoefZ*Computed Z + TideHeight where TideHeight and CoefZ may only be obtained using seatruth |
![]() TCC of water column corrected bottom reflectance * No enhancement: radiances are BOA: this is a "low tide view" * The dark diatom ooze area is well visible in the southern part of Hamelin Pool | ![]() average bottom reflectance B * The processing of darkest areas required the introduction of special conditions in 4SM code * These areas at a depth of 2-5 m have a quasi-null reflectance in the blue band: depth results are all the more questionable |
