Class WebMercatorTileGrid

io.jmix.mapsflowui.kit.component.model.WmtsTileGrid

io.jmix.mapsflowui.kit.component.model.WebMercatorTileGrid

public class WebMercatorTileGrid
extends WmtsTileGrid

A WmtsTileGrid preset for the standard Web Mercator (EPSG:3857) tile matrix set. The constructor fills the inherited tile-grid geometry (resolutions, matrix identifiers, origin, extent) from a small set of parameters, so a WMTS source can be configured without spelling out the full grid by hand.

The resolutions and matrixIds cover zoom levels 0–maxZoom (in OpenLayers the array index must match the zoom level). matrixIds are matrixIdPrefix + z (e.g. prefix "EPSG:900913:" yields "EPSG:900913:0"). Empty prefix yields bare "0","1",… as used by OGC WebMercatorQuad.

Constructor Details

WebMercatorTileGrid

public WebMercatorTileGrid()

Creates a grid for zoom levels 0–19, 256px tiles and bare numeric matrix ids.

WebMercatorTileGrid

public WebMercatorTileGrid(int maxZoom)

Creates a grid for zoom levels 0–maxZoom, 256px tiles and bare numeric matrix ids.

Parameters:

maxZoom - the maximum zoom level (inclusive)

WebMercatorTileGrid

public WebMercatorTileGrid(Integer maxZoom,
 Size tileSize,
 String matrixIdPrefix)

Creates a Web Mercator grid.

Parameters:

maxZoom - maximum zoom level (inclusive); null defaults to 19

tileSize - tile size in pixels; null defaults to 256x256

matrixIdPrefix - prefix prepended to each level index; null defaults to empty

Throws:

IllegalArgumentException - if maxZoom < 0
