growth. It was designed to provide continuity for the VGT optical instrument
from the SPOT-4 and SPOT-5 missions.
The sensor collects data in three VNIR (visible and near-infrared) bands
and one SWIR (short-wave infrared) spectral band with a 2250km field of
view. Global images are produced every 2 days at 300m resolution, and a 100m
image from nadir observations every 5 days. These images are later
composited to produce this daily synthesis dataset. The description of
the compositing and atmospheric correction procedures can be found in
the user manual.
The reflectances provided in this dataset are presented as Digital Count
Numbers (DN) and must be converted according to the guidelines in
Section 4.6.1 of the user manual.
Version C1
Proba-V is a satellite mission tasked to map land cover and vegetation
growth. It was designed to provide continuity for the VGT optical instrument
