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

Mon Nov 11 03:37:21 PST 2024

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 L1B in HDF-EOS format should be 
readable by GDAL compiled with HDF4 support without additional libraries?

Thanks for any hint.

Workflow:

Build HDF4 (4.3.0)

./configure --prefix=/home/hernan/project --disable-netcdf 
--disable-fortran --enable-shared --disable-static
make
make install

Build GDAL (3.10) with HDF4 support
ccmake , make, ... etc

/home/hernan/project/bin/gdal-config --formats
MEM vrt HDF4 MEM

Test

/home/hernan/project/bin/gdalinfo
