         //form a triangle using the angles before and after the east/north position angle
         int quadrantOffset = quadrantOffset(east, north);
         double offset = Math.atan2(Math.abs(east), Math.abs(north));
         double totalOffset = offset + quadrantOffset;
         
         double beforeAngle = 0;
