Exactly how slould i do this?
suppose i have not the 'new' crs althought i know how it should be.
Using this code
SetLayerCRSCommand setCrs = new SetLayerCRSCommand(ILayer l,
CoordinateReferenceSystem crs);
i can make the change of projection but how do i create an object
CoordinateReferenceSystem containing what i want?
Thanks.
