Code et coefficients SMAC

BACK
 

Please find in the attachments the SMAC-V4 code as well as the coefficients files for several sensors.

Coefficients filenames with "CONT" or "_1" were computed with the 6S continetal aerosol model, and "DES" is for desertic aerosols.
We did not produce yet a documentation. As you will see, the implementation of the code is rather easy to understand.SMAC is distributed for free to the scientific community, for research purposes.

The SMAC routine has been integrated in the OTB product (ORFEO Tool Box), with an open source licence.
We hope you will find SMAC useful. As far as possible, we would appreciate information on the results you will obtain with SMAC.

Sincerely yours

Gerard Dedieu

Sensors 2013 :

Quickbird (Red, Pan, NIR, Green, Blue)
Worldview2
(Yellow, Red Edge,Red, PAN, NIR2, NIR1,Green, Coastal, Blue)
Ikonos
(Red, Pan, NIR, Green, Blue)
Pléiades1A (PHR1A)
(Red, Pan, NIR, Green, Blue)
RapidEye
(Red Edge,Red, NIR,Green, Blue)
Landsat8
(Red, Pan, NIR, Green, Blue)
DMC_DEIMOS1
(Red, NIR,Green)

Quickbird, Worldview2, Ikonos, Pléiades1A (PHR1A), RapidEye coefficients were computed by Magellium for CNES

Landsat8 and DMC_DEIMOS1 were computed by Olivier Hagolle at CESBIO

In both cases, the coefficients have been computed thanks to a specific new tool developed by B. Berthelot at Magellium for CNES

Sensors 2009 :

METOP
AVHRR3
(VIS, NIR, MIR)
LISS3
(B2, B3, B4, B5)
AWIFS
(B2, B3, B4, B5)

The coefficients for the following sensors were computed by Béatrice Berthelot  (VEGA Technologies SAS) with funding by VITO-Belgium

Coefficients filenames for all these sensors :

ASTER
ATSR
MERIS
METEOSAT
MISR
MODIS
MSG
SeaWifs
SPOT
VEGETATION

These new coefficients were computed by O.Hagolle at CNES. Although no one complained yet, the validation of these coefficients was very basic :

NOAA7, NOAA17, NOAA18 (instrument AVHRR)
LANDSAT4, LANDSAT5, LANDSAT7 (instrument TM ou ETM) FORMOSAT-2 (instrument RSI)
