      • latlon2eastNorth

        default EastNorth latlon2eastNorth​(LatLon ll)
        Convert from lat/lon to easting/northing.

        This method exists to not break binary compatibility with old plugins

        Parameters:
        ll - the geographical point to convert (in WGS84 lat/lon)
        Returns:
        the corresponding east/north coordinates
        See Also:
        ILatLon.getEastNorth(Projecting)

      • latlon2eastNorth

        EastNorth latlon2eastNorth​(ILatLon ll)
        Convert from lat/lon to easting/northing. This method uses the newer ILatLon interface.
        Parameters:
        ll - the geographical point to convert (in WGS84 lat/lon)
        Returns:
        the corresponding east/north coordinates
        Since:
        12161
        See Also:
        as shorthand.

      • eastNorth2latlonClamped

        LatLon eastNorth2latlonClamped​(EastNorth en)
        Convert a east/north coordinate to the LatLon coordinate. This method clamps the lat/lon coordinate to the nearest point in the world bounds.
        Parameters:
        en - east/north
        Returns:
        The lat/lon coordinate.

      • getBaseProjection

        Projection getBaseProjection()
        Gets the base projection instance used. This may be the same as this one or a different one if this one is translated in east/north space.
        Returns:
        The projection.

      • getProjectingsForArea

        java.util.Map<ProjectionBounds,​Projecting> getProjectingsForArea​(ProjectionBounds area)
        Returns an map or (subarea, projecting) paris that contains projecting instances to convert the coordinates inside the given area. This can be used by projections to support continuous projections. It is possible that the area covered by the map is bigger than the one given as area. There may be holes.
        Parameters:
        area - The base area
        Returns:
        a map of non-overlapping ProjectionBounds instances mapped to the Projecting object to use for that area.

      • getCacheKey

        default java.lang.Object getCacheKey()
        Gets the object used as cache identifier when caching results of this projection.
        Returns:
        The object to use as cache key
