I'm not very familiar with the ArcGIS tools provided for netCDF data, but you may find that one of the tools mentioned in the answer to this FAQ is better: How do I convert netCDF data to ASCII or text? http://www.unidata.ucar.edu/netcdf/docs/faq.html#converttotext A short Python program may be the shortest and clearest way to solve this problem, but the user would have to have some familiarity with one of the Python interfaces to netCDF, such as http://code.google.com/p/netcdf4-python/ --Russ Russ Rew UCAR Unidata Program address@hidden http://www.unidata.ucar.edu Ticket Details =================== Ticket ID: MLE-377600 Department: Support netCDF Priority: Normal Status: Closed
