Tile	findRightNeighbour(Tile tile, TileService service) Finds the tile for a service at the given position and zoom level, which is immediately to the right of the passed tile.
Tile	findTileAtCoordinate(double lon, double lat, ZoomLevel zoomLevel, TileService service) Return a tile with the proper row and column indexes.
Tile	findUpperLeftTile(double lon, double lat, WMTSZoomLevel zoomLevel, WMTSTileService service) Find the first valid Upper Left tile for the current layer.

Method Detail

create

public Tile create(TileIdentifier identifier,
                   TileService service)

Description copied from class: TileFactory

Creates a new tile for the given position using a service.

Specified by:

create in class TileFactory

Returns:

findTileAtCoordinate

public Tile findTileAtCoordinate(double lon,
                                 double lat,
                                 ZoomLevel zoomLevel,
                                 TileService service)

Return a tile with the proper row and column indexes.

Please notice that the tile indexes are purely computed on the zoom level details, but the MatrixLimits in a given layer may make the row/col invalid for that layer.

Specified by:

findTileAtCoordinate in class TileFactory

Parameters:

lon - the longitude

lat - the latitude

zoomLevel - the zoom level

service - the service

Returns:

a tile

findUpperLeftTile

public Tile findUpperLeftTile(double lon,
                              double lat,
                              WMTSZoomLevel zoomLevel,
                              WMTSTileService service)

Find the first valid Upper Left tile for the current layer.

getLimits

public static TileMatrixLimits getLimits(TileMatrixSetLink tmsl,
                                         TileMatrixSet tms,
                                         int z)

constrainToUpperLeftTile

public WMTSTile constrainToUpperLeftTile(Tile matrixTile,
                                         WMTSZoomLevel zl,
                                         WMTSTileService service)

If the tile is outside the limits, take a valid one which can be used to start a loop on.

getZoomLevel

public WMTSZoomLevel getZoomLevel(int zoomLevel,
                                  TileService service)

Description copied from class: TileFactory

Gets the ZoomLevel (object) for a given zoom level integer.

Specified by:

getZoomLevel in class TileFactory

Parameters:

zoomLevel - the zoom level

service - the service

Returns:

a zoom level

findRightNeighbour

public Tile findRightNeighbour(Tile tile,
                               TileService service)

Description copied from class: TileFactory

Specified by:

findRightNeighbour in class TileFactory

Parameters:

tile - the reference tile

findLowerNeighbour

public Tile findLowerNeighbour(Tile tile,
                               TileService service)

Specified by:

findLowerNeighbour in class TileFactory

Parameters:

tile - the reference tile

getExtentFromTileName

public static ReferencedEnvelope getExtentFromTileName(WMTSTileIdentifier tileIdentifier,
                                                       TileService service)
