Greetings Alessio,

I am unsure. I would check the comments here, as well as the code:

https://github.com/Unidata/thredds/blob/master/cdm/src/main/java/ucar/unidata/geoloc/projection/RotatedLatLon.java

Cheers,

Sean

> Hi,

> double param2 = grid_south_pole_longitude
> double param3 = grid_south_pole_angle

> RotatedLatLon rot2 = new RotatedLatLon(param1, param2, param3);
> ProjectionPoint pp = new ProjectionPointImpl(lon, lat);
> LatLonPoint ll2 = rot2.projToLatLon(pp);
