Satellite Images 2021-2023
Browse filesThe images are in geoTIFF format and can be read in GIS file or R using the raster package. The files are in stack format meaning that for a given date several images correspond to the indices. With 10 m resolution there are 14 images with the following correspondence :
Rasters in the stack:
- Stack with 10 m resolution: B2, B3, B4, B8, ndvi, savi, tsavi, msavi2, evi, gcvi, ndwi, fapar, fcover, lai (14 rasters)
- Stack with 20 m resolution: B11, B12, B5, B6, B7, B8A, bdre, nbr, resi, ndmi (10 rasters)
Details on the indices are in the description of file HuggingFace_Sat_2021-2023.csv of this data repository.
The data were processed by INRAE – EMMAH group. Sentinel 2 level 2A images were uploaded from the Copernicus site. Biophysical variables were computed using 10 m resolution band and the bvnet algorithm (Weiss et al 2002).
