ArcGis

TIP

加载 ArcGis 影像数据。

代码如下:

点我查看代码

<template>
  <div id="map"></div>
</template>

<script lang="ts" setup>
import { onMounted, onBeforeUnmount } from "vue";
import { Map, View } from "ol";
import { Tile } from "ol/layer";
import { XYZ } from "ol/source";
import { ATTRIBUTIONS } from "../../../constants";

let map: Map | null = null;

const arcGISLayers = new Tile({
  source: new XYZ({
    attributions: ATTRIBUTIONS,
    url:
      "http://server.arcgisonline.com/ArcGIS/rest/services/" +
      "World_Topo_Map/MapServer/tile/{z}/{y}/{x}",
  }),
});
const initMap = () => {
  return new Map({
    //初始化map
    target: "map",
    //地图容器中加载的图层
    layers: [],
    //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
      zoom: 5, //地图初始显示级别
    }),
  });
};

onMounted(() => {
  map = initMap();
  //添加瓦片地图图层
  map.addLayer(arcGISLayers);
});

onBeforeUnmount(() => {
  if (map) {
    map.dispose();
    map = null;
  }
});
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
