Hi again, I spoke too soon! A little more research on our end uncovered a bug in how we were reading the bytes that describe the GDS template. When we fixed the bug, we get a new error: "Grid Definition Section 32768 not supported" So, we'll have to get together an implementation for this grid. Many thanks for bringing this to our attention. Cheers, Lansing Ticket Details =================== Ticket ID: HVC-591098 Department: Support netCDF Java Priority: Normal Status: Closed
