Project Main Steps

Timeline

The VEGETATION instrument is an imaging system in 4 spectral bands : blue (0.43-0.47 microns), red (0.61-0.68 microns), near infrared (0.78-0.89 microns), and SW infrared (1.58-1.75 microns).
The red and near infrared are particularly well adapted to describe the vegetation photosynthesis activity, while the SW infrared is a good detector for the ground and vegetation humidity. The blue, is designed in this case to make atmospheric corrections.
VEGETATION uses telecentric optics giving a quasi constant spatial resolution through the field of view, particularly wide (2 200 km on the ground) : this resolution is 1.15 km at nadir, and still 1.7 km on the sides of the field of view (101°).
