Hi John, hi all, I know that for Topex/Poseidon and Jason-1/2 satellite data a specific reference ellipsoid is used. If ESRI pick a sample of Jason data, as far as I remember this reference ellipsoid is declared in the netCDF files. They can retrieve these data on this FTP directory: ftp://avisoftp.cnes.fr/AVISO/pub/jason-2/ssha_gdr_t/
Hope this helps. Olivier. -----Message d'origine----- De : [email protected] [mailto:[email protected]] De la part de John Caron Envoyé : mardi 1 février 2011 20:40 À : [email protected]; Java NetCDF Objet : [CF-metadata] ESRI implementation of ellipsoidal-earth Apparently ESRI is willing to add support for CF 1.5 grid_mapping attributes for ellipsoidal-earth/geodetic-datum definitions in the Grid Mappings and Projections specification. They are looking for sample data, especially using ellipsoidal parameters (semi_major_axis/semi_minor_axis/inverse_flattening). Does anyone have any? Also, they are wondering what to use for the default ellipsoid when these are not specified. It seems to me the obvious candidates are 1) spherical earth with a standard radius, or 2) WGS84 ellipsoid. Opinions?
