Constructor Detail

ShiftedProjecting

public ShiftedProjecting(Projecting base,
                         EastNorth offset)

Create a new ShiftedProjecting

Parameters:

base - The base to use

offset - The offset to move base. Subtracted when converting lat/lon->east/north.

Method Detail

latlon2eastNorth

public EastNorth latlon2eastNorth(ILatLon ll)

Description copied from interface: Projecting

Convert from lat/lon to easting/northing. This method uses the newer ILatLon interface.

Specified by:

latlon2eastNorth in interface Projecting

Parameters:

ll - the geographical point to convert (in WGS84 lat/lon)

Returns:

the corresponding east/north coordinates

See Also:

as shorthand.

eastNorth2latlonClamped

public LatLon eastNorth2latlonClamped(EastNorth en)

Description copied from interface: Projecting

Convert a east/north coordinate to the LatLon coordinate. This method clamps the lat/lon coordinate to the nearest point in the world bounds.

Specified by:

eastNorth2latlonClamped in interface Projecting

Parameters:

en - east/north

Returns:

The lat/lon coordinate.

getBaseProjection

public Projection getBaseProjection()

Description copied from interface: Projecting

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.

Specified by:

getBaseProjection in interface Projecting

Returns:

The projection.

getProjectingsForArea

public java.util.Map<ProjectionBounds,Projecting> getProjectingsForArea(ProjectionBounds area)

Description copied from interface: Projecting

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.

Specified by:

getProjectingsForArea in interface Projecting

Parameters:

area - The base area

Returns:

a map of non-overlapping ProjectionBounds instances mapped to the Projecting object to use for that area.
