Hi all,
I noticed, what I believe is an Error when converting a Byte Image from
geotiff to Netcdf. In the newest Gdal Version (trunk from Monday), it
reports the correkt NoData Value (in older gdal Version i tested this
1.11 this was also incorrekt) but it reports the _FillValue as -1 while
reporting that the Dataset is _Unsigned. This looks like the FillValue
is written as a signed byte (For Na=254 it reports fillvalue=-2).
Is this difference between noData and _FillValue intentional? And is
there any way to "fix" the FillValue in my Netcdf ?
I ran gdal_translate example.tif example.nc -of netCDF
The tiff reports the (korrekt) NaValue as :
Band 1 Block=2000x4 Type=Byte, ColorInterp=Gray
NoData Value=255
While in the NetCDF I get :
Band 1 Block=2000x1 Type=Byte, ColorInterp=Undefined
NoData Value=255
Metadata:
grid_mapping=transverse_mercator
long_name=GDAL Band Number 1
NETCDF_VARNAME=Band1
valid_range={0,255}
_FillValue=-1
_Unsigned=true
Best
Julian
