Infrared and Visible Optical Sensors Subgroup
CEOS-IVOS Libya-4 Workshop
Paris, France. 4-5 October 2012
Background
In the context of CEOS IVOS, the pseudo-invariant Libya-4 desert site is commonly used by several teams. A special workshop fully dedicated to the use of Libya-4 site for calibration purposes was organised by CNES in Paris on 4th and 5th October 2012.
The main topics were studies on "site characterization" (morphology, homogeneity, spectral behaviour, stability, BRDF) and on "calibration results" (inter-calibration, calibration monitoring....)
