Hi,
I'm dealing with a sample GRIB data which should be in polar stereographic
projection.
GRID definition:
http://www.nco.ncep.noaa.gov/pmb/docs/on388/tableb.html#GRID217
GRIB sample:
http://www.ftp.ncep.noaa.gov/data/nccf/com/nam/prod/nam.20150622/nam.t00z.awp21700.tm00.grib2
Note the sample is a grib2 but the grid definition should be the same.
When I'm checking the attributes setup by the NetCDF Java library, I see
this:
int PolarStereographic_Projection;
* :grid_mapping_name = "stereographic";*
:longitude_of_projection_origin = 225.0; // double
:latitude_of_projection_origin = 90.0; // double
:scale_factor_at_projection_origin = 0.9330127018922193; // double
:earth_radius = 6371229.0; // double
Taking a look to the Grib2Gds class, I see that it enters the
PolarStereographic subclass and, at line 801, it uses:
Stereographic(latOrigin, lov, scale) constructor
which internally sets its name as "stereographic";
Moreover, the alternative constructor:
public Stereographic(double lat_ts_deg, double latt_deg, double lont_deg,
boolean north) {
super("PolarStereographic", false);
...
which set the name as "PolarStereographic" seems is never used around in
the code.
Is it the expected behavior?
Thanks for your assistance.
Cheers,
Daniele
