I am looking for IDL code to read general (i.e. structure not pre-defined) HDF
SDS datafiles. I thought I'd check before I start writing one. The module(s) I
need should be able to inventory the contents of a HDF file containing multiple
SDS entries, with each SDS being of arbitrary type and number of dimensions,
and having an arbitrary number of attributes. This inventory would preferably
be presented as a widget list, and allow the user to select a variable by name.
The user would then be presented with a new widget dialog box that asks the
user to select the dimensions of the data hyperslab to be read.
I realize that this is a tall order, but perhaps someone has already written
some code to do it. I have looked at the Data and Dimensions Interface (DDI)
package available at
http://www.nersc.gov/doc/Services/Applications/Graphics/DDI/ DDI.html
but I could not get it to work properly. If anyone is using DDI to import HDF
SDS data into IDL I would like to hear from them. Likewise, if there is another
similar package available I would also like to hear about it.
Cheers,
Liam.
