Optical calibration, bathymetry, water column correction and bottom typing of shallow marine areas, using passive remote sensing imageries
Busy? 4SM in 10 lines
Review of some papers collected on the net
This review shows how hot this area of R&D still is!

Alexey Castrodad Carrau
A remote sensing method for resolving depth and subpixel composition of aquatic benthos
"The technique requires knowledge
of the reflectance spectra of m pure substrata in n (n>m) spectral bands at depth 0
and the water diffuse attenuation coefficients for the site in the same bands.
Depth, z, can be entirely unknown."
|PHD work done in 2005 at U of Nebraska Ikonos image |
Great reading indeed : a fine "digest" of the whole bio-optical theories!
An all-included service!
I just wish I had that culture and those brains!
I just wish I had a few months for delivering
a bathymetric map and a bottom type classification
for just one Ikonos image for my PHD assignement
at an affordable price!
Shows that a more operational solution is still wanted!
Not operational by lay practionners for quite a long while though
While waiting, use 4SM
I just wish I'd be given the oportunity
to show what 4SM can do with this HYMAP imagery
over a week or so.
I'm afraid though that the Hymap lines might not include proper deep waters.
"Influence of atmospheric and sea-surface corrections on retrieval of bottom depth and reflectance
No need for such analytical niceties for case 1 waters though:
4SM can process several tens of bands in clear waters
in a matter of just a few days
I wish I would be given the opportunity
to show what 4SM can do
with these IKONOS images
in just a fraction of the time
