Computed Min/Max=15.000,17547.000 Again, sorry for the noise and thanks for the -mm hint, MM :) best, Vero 2018-02-05 20:54 GMT+01:00 Veronica Andreo <veroand...@gmail.com>: > Forgot the list, sorry... > > ------- > > Hi Markus, > > here the output of gdalinfo -mm for the same band reported earlier: > > gdalinfo -mm T21KZP_20171212T134159_B01.jp2 > Driver: JP2OpenJPEG/JPEG-2000 driver based on OpenJPEG library > Files: T21KZP_20171212T134159_B01.jp2 > [...] > > Band 1 Block=192x192 Type=UInt16, ColorInterp=Gray > Min=908.000 Max=1511.000 Computed Min/Max=934.000,6934.000 > Minimum=908.000, Maximum=1511.000, Mean=1138.806, StdDev=74.933 > Overviews: 915x915, 457x457, 228x228, 114x114 > Overviews: arbitrary > Metadata: > STATISTICS_MAXIMUM=1511 > STATISTICS_MEAN=1138.8064 > STATISTICS_MINIMUM=908 > STATISTICS_STDDEV=74.933459275813 > Image Structure Metadata: > COMPRESSION=JPEG2000 > NBITS=15 > > still differs a lot from what I get after importing into GRASS. > > System Info > > GRASS version: 7.5.svn > > GRASS SVN revision: r72203 > > Build date: 2018-01-01 > > Build platform: x86_64-pc-linux-gnu > > GDAL: 2.1.3 > > PROJ.4: 4.9.3 > > GEOS: 3.6.1 > > SQLite: 3.20.1 > > Python: 2.7.14 > > wxPython: 3.0.2.0 > > Platform: Linux-4.14.14-200.fc26.x86_64-x86_64-with-fedora-26-Twenty_Six > > best, > Vero > > > 2018-02-05 19:49 GMT+01:00 Markus Metz <markus.metz.gisw...@gmail.com>: > >> >> >> On Mon, Feb 5, 2018 at 1:14 PM, Veronica Andreo <veroand...@gmail.com> >> wrote: >> > >> > I tested also with 74 release branch... same result >> > >> > 2018-02-05 13:05 GMT+01:00 Veronica Andreo <veroand...@gmail.com>: >> >> >> >> Hi devs >> >> >> >> I'm testing Martin's new add-on, r.sentinel.import.
