Hi All,

How to define a custom Proj4js.def["myown"] when it is not in http://spatialreference.org/ref
but when I have the following projection parameters? Can FWTOOLS help me doing this?

> polar_stereographic:straight_vertical_longitude_from_pole = 263.f ;
> polar_stereographic:standard_parallel = 60.f ;
> polar_stereographic:false_easting = 3450000.f ;
> polar_stereographic:false_northing = 7450000.f ;
> polar_stereographic:latitude_of_projection_origin = 90.f ;
> polar_stereographic:grid_mapping_name = "polar_stereographic" ;
> polar_stereographic:resolution_at_standard_parallel = 50000.f ;

For example, using http://spatialreference.org/ref/epsg/32661/proj4js/ for universal polar stereographic (which is usefull when used for area above the 60 degrees north ), I get Proj4js.defs["EPSG:32661"] = "+proj=stere +lat_0=90 +lat_ts=90 +lon_0=0 +k=0.994 +x_0=2000000 +y_0=2000000 +ellps=WGS84 +datum=WGS84 +units=m +no_defs";

Regards,

Stephane
