[gdal-dev] Are all Files of HDF5 Formats supported by Gdal with libhdf5?

[atubar]

Hi, I'm not quite sure about what you need to analyze the problem. But I will write down all details which I consider helpful.

I build all dlls (gdal_HDF5.dll, gdal_HDF5Image.dll), add C:\gdal\gdal162\bld\bin as system variable.

Then I reset VS2008 as VC++ with default settings, add C:\gdal\gdal162\bld\include and C:\gdal\gdal162\bld\lib to the project.

The sample datas are supplied as part of software package. Theit file structures are below read out by The HDF hdfview 2.5.

-----------Structure of sample data from hdfview 2.5----------------

   printf( "Pixel Size = (%.6f,%.6f)\n",
                adfGeoTransform[1], adfGeoTransform[5] );
  }
 }
 
 GDALClose(poDataset);
 return 0;
