While I am not sure what you mean by "access", but first, let's have a look at the structure of the "data" variable. After you read the data, please call these two functions: visad.jmet.DumpType.dumpMathType(data.getType()); and visad.jmet.DumpType.dumpDataType(data); This should produce text output that will describe the structure of your "data" and may help. I should add this: I am surprised that any of that old HDF code works at all...NCSA has not supported it for at least ten years! We have pretty much been abandon by them, and instead are relying more on the netcdf-java library from Unidata to provide access to HDF files; although this does not produce a VisAD Data object, it does allow one to read the variables and their associated metadata which can then be used to construct Fields as needed. tom 2011/3/28 Juanjo González <juanjose.gonzalez@xxxxxxxxx>: > Dear Mr/Madam, > > I finally succeed on compiling VisAD library.
