Re: [gdal-dev] Gdal_translate into HDF4 fails
Cool, i tired and actually works, but just a question, is it normal that using gdal_translate -of netCDF -co FORMAT=NC4 the resulting image is rotated by 180° (Upside down)?

if you gdal_translate -of netCDF -co FORMAT=NC4 , the resulting netCDF file will actually be a HDF5 file (with netCDF "decorations"): - https://gdal.org/drivers/raster/netcdf.html#creation-options - https://www.unidata.ucar.edu/software/netcdf/docs/interoperability_hdf5.html Le 18/02/2022 à 15:24, Lorenzo Di Giacomo a écrit : Hi guys, i was reading the question and i was wondering if it's possibile do the same translate operation with HDF5, like: gdal_translate -of HDF5Image 3band.tif out.h5, i tried but doesn't work and says " HDF5 driver has no creation capabilities."

Re: [gdal-dev] Gdal_translate into HDF4 fails
Hi, That HDF5 driver is read-only is documented in https://gdal.org/drivers/raster/hdf5.html so that the driver capabilities are missing Supports CreateCopy() and Supports Create() Same metadata is available with gdalinfo --format [format_name]. (But metadata is wrong for HDF4 and capabilities are missing, I wonder how to fix that) gdalinfo --format hdf4 Format Details: Short Name: HDF4 Long Name: Hierarchical Data Format Release 4 Supports: Raster Supports: Multidimensional raster Extension: hdf Help Topic: drivers/raster/hdf4.html Supports: Raster subdatasets Supports: Open() - Open existing dataset. -Jukka Rahkonen- Lähettäjä: Lorenzo Di Giacomo Lähetetty: perjantai 18. helmikuuta 2022 16.24 Vastaanottaja: Even Rouault Kopio: Rahkonen Jukka (MML) ; 'gdal-dev@lists.osgeo.org' (gdal-dev@lists.osgeo.org) Aihe: Re: [gdal-dev] Gdal_translate into HDF4 fails Hi guys, i was reading the question and i was wondering if it's possibile do the same translate operation with HDF5, like: gdal_translate -of HDF5Image 3band.tif out.h5, i tried but doesn't work and says " HDF5 driver has no creation capabilities."

Hi guys, i was reading the question and i was wondering if it's possibile do the same translate operation with HDF5, like: gdal_translate -of HDF5Image 3band.tif out.h5, i tried but doesn't work and says " HDF5 driver has no creation capabilities."
