  className: "天地图影像图层",
  source: new XYZ({
    attributions: ATTRIBUTIONS,
    url: "http://t0.tianditu.com/DataServer?T=img_w&x={x}&y={y}&l={z}&tk=3bc6874f2b919aa581635abab7759a3f",

let map: Map | null = null;
onMounted(() => {
  map = new Map({
    //地图容器div的ID
    target: "map",
    //地图容器中加载的图层
    layers: [
      //加载瓦片图层数据
      raster,
    ],
    //地图视图设置
    view: new View({
      projection: "EPSG:4326", // 坐标系，有EPSG:4326和EPSG:3857
      //地图初始中心点
      center: [114.064839, 22.548857], // 深圳坐标
      //地图初始显示级别
      zoom: 12,
