Hi All,
I am trying to display HDF5 files directly in MapServer without converting them. To test
the HDF library with GDAL, I first converted a subset (gdal_translate -of GTiff
HDF5:"METEOSAT_7_MVIRI_GLOBEWV_2003_02_20_12_00_00.h5"://image1/image_preview
meteopreview.tif). This tiff can be viewed with MapServer, so i assume the HDF5 library
is correctly implemented in GDAL.
Now I want to directly open the HDF5 file in mapserver. This gives me an error. ("
The server encountered an internal error or misconfiguration and was unable to complete
your request.")
The Apache error log looks like this:
Appache Error Log:
[Tue Jan 22 11:45:34 2008] [error] [client 145.23.130.25] malformed header from
script. Bad header=szFilenname /nobackup/users/pl: mapserverhdf.cgi
[Tue Jan 22 11:45:34 2008] [error] Failed to change_hat to
'HANDLING_UNTRUSTED_INPUT'
And the mapfile looks like this (part of):
MapFile:
LAYER
NAME preview
DATA
'HDF5:/nobackup/users/plieger/mapdata/METEOSAT_7_MVIRI_GLOBEWV_2003_02_20_12_00_00.h5://image1/image_preview'
#DATA 'meteopreview.tif'

lat_0=0
h=35807.250000
a=6378.134766
b=6356.750488
END
END
(When i switch the data statement to tiff it works, otherwise it gives me an
error (see the # sign).)
I use a script that sets the LD_LIBRARY_PATH and the LD_RUN_PATH to the correct
path, this script calls in turn mapserver. Therefore I think that there is no
problem with the libraries. It also works with all the other libraries. I have
to use this script because I have no admin rights, (and i won't get them).
Can anyone help me with this problem, or had the same problem?
Thanks in advance,
Maarten
