Hi,
I'm attempting to set up Thredds 4.0 to serve HDF5 files through opendap.
The HDF5 files contains 11 image groups 'image1' to 'image11'. In each
group the data is contained in the variable 'image_data'.
As a test example I have added the following lines to catalog.xml:
<datasetRoot path="msg/level2" location="/data/msg/level2" />
<dataset name="Test MSG" ID="testMSG" serviceName="dapService"
urlPath="msg/level2/level2_MSG2_8bit_VISIR_STD_20091005_0700.H5"
dataType="Grid">
<dataFormat>HDF5</dataFormat>
</dataset>
Now the dds of the data URL returns:
Dataset {
Float32 geo_ref_tiepoints[1][5041];
Byte image_data[3712][3712];
Byte image_preview[96][96];

} msg/level2/level2_MSG2_8bit_VISIR_STD_20091005_0700.H5;
It seems all information regarding the HDF5 groups have been lost and
I'm unable to distinguish between the different variables.
Is it not possible to serve HDF5 with groups through opendap on TDS or
have I missed something in the setup?
Best regards
