Hi,
I'm having a trouble with viewing this Swath file with IDV.
Here's a test URL you can try.
http://hdfdap.hdfgroup.uiuc.edu:8889/opendap/data/MOD.hdf
I believe it's related to one of the attributes below because I can
see a data without problem if I suppress all of them.
Here's a screen shot that works without attributes:
http://hdfdap.hdfgroup.uiuc.edu:8889/opendap/data/MOD10_L2.A2000136.0235.004.2003009030119.hdf.snow_cover.idv.without_attr.PNG
Can anyone point out which attribute causes IDV to stop treating it
as DODS Grid file?
