Both netCDF and HDF can be used for point set data, if I'm correctly interpreting what you mean by that: values at each point for a set of points that are not on a grid. For a netCDF example, see the appended CDL file. --Russ _____________________________________________________________________ Russ Rew UCAR Unidata Program russ@xxxxxxxxxxxxxxxx http://www.unidata.ucar.edu netcdf metar { dimensions: maxAutoStaLen = 6;
