I don't know anything about EKKO_3D, T3D or .HDL but I see that GDAL appears to partially (?) support HDF volumes: bartok:gdal[12761.3] grep -i vol frmts/hdf4/* frmts/hdf4/hdf4imagedataset.cpp: an image at a time to form a volume. frmts/hdf4/hdf4imagedataset.cpp: A rank 4 dataset may be thought of as a series of volumes. frmts/hdf4/hdf4imagedataset.cpp: case 4: // 4Dim: volume-time frmts/hdf4/hdf4imagedataset.cpp: case 3: // 3Dim: volume frmts/hdf4/hdf4imagedataset.cpp: case 4: // 4Dim: volume frmts/hdf4/hdf4imagedataset.cpp: case 3: // 3Dim: volume frmts/hdf4/hdf4imagedataset.cpp: case 3: // 3Dim: volume What does 'gdalinfo' say about this data set? That's probably the starting point. ciao Markus ------------------ ITC -> dall'1 marzo 2007 Fondazione Bruno Kessler ITC -> since 1 March 2007 Fondazione Bruno Kessler ------------------ _______________________________________________ grassuser mailing list [email protected] http://grass.itc.it/mailman/listinfo/grassuser
