I am trying to read an image inside HDF5 file. According to the IDL Reference this should be pretty straight forward using the following code.
file = '***.HDF5'
fileId = H5F_OPEN(file)
ndviDataset = H5D_OPEN(fileId, '/LEVEL3/NDVI/NDVI')
ndviImage = H5D_READ(ndviDataset)
H5F_CLOSE, fileId
When running this code, I always get error: H5D_READ: can't read data: Object ID:83886129
The same thing happens if I try to open the image using graphical interface H5_BROWSER(file). Any idea what is wrong? It looks like broken data, however
HDFView can open it without read error.
Thanks.

Perhaps you need to open the group, LEVEL3, and then the group NVDI, before you can read it? i.e. using the H5G* commands?
