[gdal-dev] Difficulties reading a ODIM HDF5 file

Tue Mar 12 03:25:20 PDT 2013

Hello,

I have problems reading a HDF5 ODIM file containing weather radar data.
ODIM is the Opera Data and Information Model (http://www.eumetnet.eu/opera)

The file is from the Norwegian met. Office www.met.no<http://www.met.no>.
It is nicely described in their GDAL 1.6.3.
I can also open the file in HDFView(2.6).

This is the error output I get from GDAL(1.9.0)/HDF5(1.8.5) on Windows.
The output from GDAL(1.6.3)/HDF5(1.8.4) on Linux is below.

Anyone knowing what causes this?

Regards,
Sjur Kolberg
