Re: [gdal-dev] Creating NetCDF dataset with sub datasets

My investigation, might be an issue for the github : band->SetMetadataItem("NETCDF_VARNAME", "foo"); will generate a netCDF band name of "foo1" because there must be a non-null papszExtraDimNames for some reason (netcdfdatasetp.cpp:9630) However -in order for "papszExtraDimNames" to be non-null

Re: [gdal-dev] FW: [External] : GDAL 3.8.4 build on windows failed at linking

Not the answer you'll probably want to hear, but: - Use an up-to-date compiler - Use package distributions like vcpkg or conda-forge that already brings all the dependencies "for free" - It seems you mix builds of different compilers (VS vs mingw). That's a bit asking for troubles ;-) Le 1

Re: [gdal-dev] Segmentation fault (core dumped) occurs when running ogr2ogr command on container

Hi, I had a try with your dataset on Windows and I had no segmentation fault. Perhaps not surprise because I do not use the same container than you. I had some encoding problem but I believe that it is not related. But perhaps you have some use for knowing that the unzipping part is not necessa

Re: [gdal-dev] Utilizing GDAL for adding overviews layer in python language

Hi, You could use gdal to write a single tiff file from each numpy array layer and name it accordingly: base.tif - your input tiff file base.tif.ovr - first overview base.tif.ovr.ovr - second overview base.tif.ovr.ovr.ovr - third overview etc. gdal would know to read these overviews automatically

Re: [gdal-dev] Testing the driver

Even, you are right! [cid:image002.png@01DA745F.C8585C00] So, the driver only creates a folder if it’s the last one of a path (with no extension) because this is the place where to write a set of files (a layer). So, thanks again! At this time, if I’m not wrong only there is one red light Merge

Re: [gdal-dev] Utilizing GDAL for adding overviews layer in python language

Hi, External overviews that gdaladdo creates when the -ro option is used are TIFF files with a file name extension .ovr. If you can create similar TIFFs with the other library and name them as .ovr then GDAL should use them automatically. -Jukka Rahkonen- Lähettäjä: gdal-dev Puolesta Pradeep

Re: [gdal-dev] Utilizing GDAL for adding overviews layer in python language

Hi, So you are saying that you used gdal buildoverview in Python to add overviews to the tiff file but it only uses CPU and not GPU. And you could use the other library to add overviews using GPU - can you share which library you used or what's the output format that you got? Maybe you can combine
