Venkat,
I am sorry. Your previous e-mail didn't show the SUBDATASET and then I assumed that you are dealing
with one unsupported flavor of HDF. But if it showing, great!
If you could use gdal_translate to convert to GeoTIFF you can use the same identification string on
a DATA parameter.
So, if you ran gdal_translate like that:
{{{
gdal_translate
HDF5:OMI.he5://HDFEOS/GRIDS/OMI_Column_Amount_O3/Data_Fields/ColumnAmountO3
output.tif
}}}
Then you should be able to use the same identification on your map file like
that:
{{{
LAYER
TYPE RASTER
DATA
"HDF5:OMI.he5://HDFEOS/GRIDS/OMI_Column_Amount_O3/Data_Fields/ColumnAmountO3"
}}}
Some time ago I reported a bug in Mapserver that was preventing those complex GDAL connection string
to work but I believe its fixed now.
Please, give it a try and let us know if it works or not. And don't forget to mention the GDAL and
Mapserver version that you are using.
Regards,
Ivan

Hi Ivan,
gdalinfo is showing subdataset list also, the previous mail contains
gdalinfo of one of subdataset. I have used gdal_translate to convert
the following in GeoTIFF image, however i don't have idea about how to
create layer for the given hdf subdataset.
the below is the gdalinfo showing subdataset list:

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
