|4SM has been developped, as a personnal project, then as a hobby, in almost complete isolation, since 1994. |
Using first a database of SPOT images, then a very few Landsat TM images.
Then using a number of CASI hyperspectral images, and even an AAHIS image.
Then using Landsat TM/ETM, HYPERION and OLI images, thanks to USGS's Glovis service.
Then using WV2 thanks to Digital Globe.
In 2013-2015, it has matured remarkably with the introduction of several breakthroughs using OLI, WV2, CASI, HYPERION and even HICO data.
Starting in 2009, I was paid good money by a proeminent consultancy firm for projects using Landsat or WV2 in Tanzania, Bahamas, Bahrain, Western Australia, Seychelles, Red Sea, and the UAE.
As for the UAE project, first for a limited AOI in 2013, then for an extension six months later, then for a further extension two years later.
End december 2013
I joined HYPHOON to process a CASI image of Heron Island, Australia
then in april 2014 I posted a demonstration for this studycase
October 2014, processed a HYPERION image of Fakarava atoll, French Polynesia
January 2015 processed a HICO image of Lee Stocking Island, Bahamas
|February 2015 |
processed a pansharpened QUICKBIRD image
Mapping the spatial variations of
the spectral diffuse attenuation coefficient over the Landsat 8 scene
"I don't understand
if you do also use the other bands + Pan"
Over the last four years,
4SM has become far more capable
(I know: hard to keep up!!).
Time has come when the major step forward on the part of data providers should be:
Please give us access to images with decent Noise-equivalent change in radiance
for the purpose of shallow water work.
See below: this striping in OLI images is a shame!
