Example of a WMTS source created from a WMTS capabilities document.

This example shows how to create the configuration for accessing a WMTS from a GetCapabilities response. The WMTS example shows how to create the configuration manually.

##### main.js

    import Map from 'ol/Map.js';
    import View from 'ol/View.js';
    import WMTSCapabilities from 'ol/format/WMTSCapabilities.js';
    import TileLayer from 'ol/layer/Tile.js';
    import OSM from 'ol/source/OSM.js';
    import WMTS, {optionsFromCapabilities} from 'ol/source/WMTS.js';

    const parser = new WMTSCapabilities();
    let map;

    fetch('data/WMTSCapabilities.xml')
      .then(function (response) {
        return response.text();
      })
      .then(function (text) {
        const result = parser.read(text);
        const options = optionsFromCapabilities(result, {
          layer: 'layer-7328',
          matrixSet: 'EPSG:3857',
        });

        map = new Map({
          layers: [
            new TileLayer({
              source: new OSM(),
              opacity: 0.7,
            }),
            new TileLayer({
              opacity: 1,
              source: new WMTS(options),
            }),
          ],
          target: 'map',
          view: new View({
            center: [19412406.33, -5050500.21],
            zoom: 5,
          }),
        });
      });
