Remember that you have to rescale these data first: https://lpdaac.usgs.gov/lpdaac/products/modis_products_table -> MOD09Q1 Terra Surface Reflectance Bands 1–2 Tile 250m 8 Day https://lpdaac.usgs.gov/lpdaac/products/modis_products_table/surface_reflectance/8_day_l3_global_250m/v5/terra -> layers ... MULTIPLY BY SCALE FACTOR ... best, Markus _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
