Only the above two TM images yield "reasonable" results.
They exhibit the same topographic trends and features.
I have managed so that they yield approximayely the same computed depth.
It shall be seen that the WV2 image
does not add any major novel feature to the description below.
|A gently sloping rocky platform, 5-10 m deep, |
followed by a deeper lagoon ~15 m deep,
and then by a series of rocky reefs,
in potent and complex hydrodynamic conditions.
This is how the litterature describes
the ~ 10 km wide shallow waters
along the coasts of WA.
|The above two Landsat images yields results |
which nicely fits with this description.
Add to it an ubiquitous cover
of sands, green seagrasses,
brown algae and very dark epiphyts.

Long sand dunes over a rocky platform
Many such dunes are observed, oriented SW-NE.
