Even, Thank you for your response. I also suspect there is some mixing going on. I will have a deeper look at that. Thank you for your time. Hernán BTW the output of the command you suggest is very much like yours: > grep HDF4 CMakeCache.txt | grep -v INTERNAL | grep -v ADVANCED //Set ON

Hernan, this works for me both with HDF4 4.2.14 as available on my system, and also against 4.3.0 built from source with the exact configure command line your provided Can you show the result of "grep HDF4 CMakeCache.txt | grep -v INTERNAL | grep -v ADVANCED" in your GDAL build directory?

Hi, I can't help you with building GDAL but I can show where to learn the difference between --formats and --format: https://gdal.org/en/latest/programs/raster_common_options.html#raster-common-options -Jukka Rahkonen- Lähettäjä: Hernán De Angelis Lähetetty: maanantai 11. marraskuuta 2024 14.

Thank you for your response, Jukka. That is interesting. I set cmake to build hdf4, cmake sees it and it does not throw errors during the build. In fact, I see: [ 38%] Built target gdal_HDF4 but the command you gave gives not HDF4 gdalinfo --format hdf4 (should be "formats" instead?) gdalin

Hi, Have you checked with gdalinfo if you have managed to build the HDF4 driver? gdalinfo --format hdf4 Your test file opens for me with GDAL from OSGeo4W. -Jukka Rahkonen- Lähettäjä: gdal-dev Puolesta Hernán De Angelis via gdal-dev Lähetetty: maanantai 11. marraskuuta 2024 13.37 Vastaanottaj

[gdal-dev] GDAL, HDF4 and MODIS L1B data

2024-11-11 Thread Hernán De Angelis via gdal-dev
I recently compiled a minimal GDAL (3.10) with HDF4 support (using HDF 4.3.0) for processing MODIS L1B data. However, the resulting command line tools cannot understand the format. Perhaps I am doing something wrong, or missing something important, or both. Do I understand correctly that MODIS
