createFromCapabilitiesMatrixSet(matrixSet, extent, matrixLimits){WMTSTileGrid}
-
import {createFromCapabilitiesMatrixSet} from 'ol/tilegrid/WMTS';
Create a tile grid from a WMTS capabilities matrix set and an optional TileMatrixSetLimits.
Name Type Description matrixSet
Object An object representing a matrixSet in the capabilities document.
extent
Extent | undefined An optional extent to restrict the tile ranges the server provides.
matrixLimits
Array.<Object> | undefined An optional object representing the available matrices for tileGrid.
Returns:
WMTS tileGrid instance.

Properties:
Name Type Description extent
Extent | undefined Extent for the tile grid. No tiles outside this extent will be requested by
TileSource
sources. When noorigin
ororigins
are configured, theorigin
will be set to the top-left corner of the extent.origin
Coordinate | undefined The tile grid origin, i.e. where the
x
andy
axes meet ([z, 0, 0]
). Tile coordinates increase left to right and downwards. If not specified,extent
ororigins
must be provided.origins
Array<Coordinate> | undefined Tile grid origins, i.e. where the
x
andy
axes meet ([z, 0, 0]
), for each zoom level. If given, the array length should match the length of theresolutions
array, i.e. each resolution can have a different origin. Tile coordinates increase left to right and downwards. If not specified,extent
ororigin
must be provided.resolutions
Array.<number> Resolutions. The array index of each resolution needs to match the zoom level. This means that even if a
minZoom
is configured, the resolutions array will have a length ofmaxZoom + 1
matrixIds
Array.<string> matrix IDs. The length of this array needs to match the length of the
resolutions
array.sizes
Array<Size> | undefined Number of tile rows and columns of the grid for each zoom level. The values here are the
TileMatrixWidth
andTileMatrixHeight
advertised in the GetCapabilities response of the WMTS, and define each zoom level's extent together with theorigin
ororigins
. A gridextent
can be configured in addition, and will further limit the extent for which tile requests are made by sources. If the bottom-left corner of an extent is used asorigin
ororigins
, then they
value must be negative because OpenLayers tile coordinates use the top left as the origin.tileSize
number | Size | undefined Tile size.
tileSizes
Array.<(number|module:ol/size~Size)> | undefined Tile sizes. The length of this array needs to match the length of the
resolutions
array.
