[GRASS-user] New AddOns for downloading and importing Sentinel products

2018-01-26 Thread Martin Landa
Hi, today I have uploaded a new toolset for downloading and importing Sentinel products, namely two modules: r.sentinel.download [1] and r.sentinel.import [2]. The first module requires Sentinelsat and Pandas library, the second GDAL with OpenJPEG. Testing and feedback welcome! Enjoy, Ma [1]

Hi Nikos, Did you consider using r.univar (with a zones map, like v.rast.stats does: https://trac.osgeo.org/grass/browser/grass/branches/releasebranch_7_2/scripts/v.rast.stats/v.rast.stats.py#L238, just with colon as separator) and using the resulting table as input to r.recode

2018-01-26 Thread Nikos Alexandris
Dear statistics experts, how can we compute the median of a floating point cover raster map, over a base map (using the conventional terminology as in r.stats.zonal)? It appears that there is no module to get the median out of floating point raster maps, using a base map as in r.stats.zonal or
