OPERATIONAL USE OF THE ORFEO TOOL BOX FOR THE VENUS MISSION The
Orfeo Tool Box open source software has been selected by the
French Space Agency (CNES) for the development of the Venus
ground segment L2 and L3 processors. The Venus (Vegetation &
Environment new micro satellite) mission is a French-Israeli
joint project designed to operate a multispectral instrument for
imaging selected scientific sites with a high revisit frequency
(2 days). The scientific mission aims at providing the principal
investigators with high spatial and spectral resolution data for
environment monitoring (5m/ 12 bands). In addition the Venus
instrument offers stereoscopic capabilities for cloud detection
and DEM generation. OTB provides the image processing framework
on which the L2 and L3 processors are being developed. The L2
processor offers advanced atmospheric correction algorithms
including water vapour and aerosol estimates based on multi-
temporal data analysis. It also provides cloud mask generation
and biophysical mapping.
