Hello, I am trying to create a NetCDF file with a GeoGrid. My data is a 200x200 grid indexed by latitude and longitude. Each grid point has a "prediction" value that is a double ranging from 0 to 1. Can I create a NetCDF file from this data? I have tried the code following but ran into trouble trying add a coordinate system. Any help in creating a NetCDF file from this data set would be appreciated. Thanks, Anthony NetcdfFileWriteable ncfile = NetcdfFileWriteable.createNew( "mypredfile"); // add dimensions Dimension latDim = ncfile.addDimension("lat", 200); Dimension lonDim = ncfile.addDimension("lon", 200); ArrayList<Dimension> dims = new ArrayList<Dimension>(); dims.add(latDim); dims.add(lonDim); ncfile.addVariable("prediction", DataType.DOUBLE, dims); Variable predvar = new Variable(ncfile, ncfile.getRootGroup(), null, "prediction"); predvar.setDataType(DataType.DOUBLE); predvar.setDimensions(dims); VariableDS predVariable = new VariableDS(ncfile.getRootGroup(), predvar, true); // ??????????????????????? // predVariable.addCoordinateSystem(new CoordinateSystem(ncfile, arg1, arg2)); ncfile.create(); ArrayDouble preds = new ArrayDouble.D2(latDim.getLength(), lonDim. getLength()); Random rand = new Random(); for (int i = 0; i < latDim.getLength(); i++) { for (int j = 0; j < lonDim.getLength(); j++) { preds.setDouble(preds.getIndex().set(i, j), rand.nextDouble()); } } ncfile.write("prediction", new int[2], preds); ncfile.close(); /* IS THIS CORRECT????? GridDataset gd = new ucar.nc2.dt.grid.GridDataset(NetcdfDataset. openDataset("mypred")); GeoGrid grid = new GeoGrid(gd, new VariableDS(ncfile.getRootGroup(), ncfile.getVariables(). get(0), true), new GridCoordSys(null, null)); ncfile.create(); grid.writeFile("mypredwithgrid"); */
