Hi Tom,I'm afraid that I've moved past the problem and don't have an example I can provide any more. I tried various solutions, including using the HDF library, which I got working for reading but not writing netCDF files. What I remember is that retrieved floating point values were wrong - they were all way too small.
I downloaded the NetCDF User's Guide and wrote my own interface entirely in Java using the RandomAccessFile class to read or write classic netCDF files. However, there is a performance penalty using this class that I hope to do some experimenting with to see if I can speed up the accesses.
However, thanks for following up. John At 02:47 PM 1/2/2012, Tom Whittaker wrote:
Hi John.... The netCDF classes in the VisAD library are there mainly to support the Plain class, and were coded many years ago. For non-VisAD Java applications, I would recommend using the netCDF-java jar file (available from Unidata: <http://www.unidata.ucar.edu/software/netcdf-java/>. I would be interested in knowing what the "file/library/Java inconsisteny" is that you are seeing, though.... I hope this helps. tom On Tue, Dec 20, 2011 at 7:11 PM, John DeVore <devore@xxxxxxxxxxxx> wrote: > Hi, > > I have been using netCDF for reading and writing scientific datasets from > Java on my Windows PC for a number of years.
