Re: [mapserver-users] How to add HDF-EOS data layer in MapServer

[Ivan Lucena]

Hi Venkat,

If gdalinfo is not showing the subdataset list, like in you case, it would be impossible to identify a dataset as your DATA parameter.

What version is the GDAL that you are using on command line? Is that the same that mapserver is using?

Note that there are some flavors of HDF products that are not supported by all version of GDAL/HDF.

Regards,

Ivan
