Method Detail

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.
