Bing Maps

Example of a Bing Maps layer.

When the Bing Maps tile service doesn't have tiles for a given resolution and region it returns "placeholder" tiles indicating that. Zoom the map beyond level 19 to see the "placeholder" tiles. If you want OpenLayers to display stretched tiles in place of "placeholder" tiles beyond zoom level 19 then set maxZoom to 19 in the options passed to ol/source/BingMaps.

main.js

import BingMaps from 'ol/source/BingMaps.js';
import Map from 'ol/Map.js';
import TileLayer from 'ol/layer/Tile.js';
import View from 'ol/View.js';

const styles = [
  'RoadOnDemand',
  'Aerial',
  'AerialWithLabelsOnDemand',
  'CanvasDark',
  'OrdnanceSurvey',
];
const layers = [];
let i, ii;
for (i = 0, ii = styles.length; i < ii; ++i) {
  layers.push(
    new TileLayer({
      visible: false,
      preload: Infinity,
      source: new BingMaps({
        key: 'Your Bing Maps Key from https://www.bingmapsportal.com/ here',
        imagerySet: styles[i],
        // use maxZoom 19 to see stretched tiles instead of the BingMaps
        // "no photos at this zoom level" tiles
        // maxZoom: 19
      }),
    })
  );
}
const map = new Map({
  layers: layers,
  target: 'map',
  view: new View({
    center: [-6655.5402445057125, 6709968.258934638],
    zoom: 13,
  }),
});

const select = document.getElementById('layer-select');
function onChange() {
  const style = select.value;
  for (let i = 0, ii = layers.length; i < ii; ++i) {
    layers[i].setVisible(styles[i] === style);
  }
}
select.addEventListener('change', onChange);
onChange();
