i.in.probav imports Proba-V NDVI data sets.
After the import the digital numbers (DN) are remapped to VEGETATION NDVI
values and the NDVI color table is applied. The imported DN map is
removed after remapping. It is also possible to change the scale and offset
factor (default is scale: 0.004, offset: -0.08 for Proba-V)
and to improve the memory usage (default is 300 MB).
Important for the Proba-V Data sets, is a user registration at
the VITO portal
necessary (Register Button in the Upper Right Corner).
The Proba-V files are delivered in NetCDF (Network Common Data Form)
format. It is required to have the GDAL libraries installed with NetCDF support.
Also to check the necessary scale and offset factor with gdalinfo.
When working with Proba-V NDVI, it it necessary to fix the range of the map because
it exceeds the -180°..+180° range with entire world extent.
You can shift the map slightly into the right position using
This example in Global datasets may help you.
