Computed depth in cm for marmion Park
 

TCC for Blue, Green and PAN

 

Computed depth Z in decimeters


 

image WZ
  • Yellow : where modeling by Yellow band
    • against Purple, Blue, Green and Pan bands
    • threshold 1.5
  • Grey : where modeling by Pan band
    • against Purple, Blue and Green bands
    • threshold 1.5
  • Green : where modeling by Green band
    • against Purple and Blue bands
    • threshold 0.5

average bottom reflectance: image B
  • bright bottoms are very scarce
    • 4SM depends on them for optical calibration
  • most bottoms are quite dark indeed:
    • thin sediment layer covered with green seagrasses
    • dark rhodolith beds
  • rocky aeolinate ridges are covered in very dark brown and green algae

image NDR: Green/Brown bottoms
  • brown bottoms would appear to denote the aeolianite rock basement, most often covered in brown vegetation (algae)
  • green bottoms would appear to denote the thin sedimentary cover, most often covered in green vegetation (seaweeds)
Bad system noise shows off!!!!!!!!

 
 
Comments
  • for seatruth, avoid using alien pixels  masked at 1 (green)
  • depth results over very dark bottoms at depth where modeling by Green against Purple and Blue are questionable, to say the least,  as green signal is virtually extinct
