OGC 地图瓦片 (地理)

渲染 OGC API 的地图瓦片 – 瓦片服务.

OGC API – Tiles 规范描述了服务是如何提供地图瓦片的。由于此规范还未最终确定，因此 OGCMapTile 资源还不是稳定 API 的一部分。

main.js

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

const map = new Map({
  target: 'map',
  layers: [
    new TileLayer({
      source: new OGCMapTile({
        url: 'https://maps.gnosis.earth/ogcapi/collections/blueMarble/map/tiles/WorldCRS84Quad',
      }),
    }),
  ],
  view: new View({
    projection: 'EPSG:4326',
    center: [0, 0],
    zoom: 1,
  }),
});
