vue利用openlayers加载天地图和高德地图

一、天地图部分

1、在vue中安装openlayers

npm i --save ol

这里说的vue是基于脚手架构建的。 新建个页面，也就是vue文件，配置好路由。接着就是可以直接放入我的代码运行显示了。

<template>

  <div class="wrapper">

    <div>天地图</div>

    <div class="map" id="olmap"></div>

  </div>

</template>

<script>

import "ol/ol.css";

import {

  tile as tilelayer } from "ol/layer";

import xyz from "ol/source/xyz";

import {

  defaults as defaultcontrols } from "ol/control";

import map from "ol/map.js";

import view from "ol/view.js";
export default {

  data() {
   return {

      map: null,

      parser: null,

    };

  },

  mounted() {
    this.initmap();

  },

  methods: {

    initmap() {

     const map = new map({
       target: "olmap",

        view: new view({

 

          center: [0, 0], //中心点经纬度

          zoom: 4, //图层缩放大小

          projection: "epsg:4326",

        }),

        controls: defaultcontrols({
          zoom: true,

          attribution: false,

          rotate: false,

        }),

      });

      this.map = map;

      // 添加地图

      let url = "http://t{0-7}.tianditu.com/dataserver?x={x}&y={y}&l={z}";

      url = `${

   url}&t=vec_c&tk=替代你的key`;

      const source = new xyz({
     url: url,

        projection: "epsg:4326",

      });

      const tdtlayer = new tilelayer({

        source: source,

      });

      this.map.addlayer(tdtlayer);

      // 添加注记

      url = "http://t{0-7}.tianditu.com/dataserver?x={x}&y={y}&l={z}";

      url = `${

   url}&t=cva_c&tk=替代你的key`;

      const sourcecva = new xyz({
        url: url,

        projection: "epsg:4326",

      });

      const tdtcvalayer = new tilelayer({

        source: sourcecva,

      });

      this.map.addlayer(tdtcvalayer);

    },

  },

};

</script>
<style scoped>

.map {

  width: 100%;

  height: 100vh;

}

</style>

天地图就可以显示出来了。

效果图：

二、高德地图部分

相对于天地图，高德地图就容易多了，直接上代码

<template>

  <div class="wrapper">

    <div>高德地图</div>

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

  </div>

</template>
<script>

import {

 map,view,feature} from 'ol'



import * as olproj from 'ol/proj'

import {

 point} from 'ol/geom'

import {

  style, fill, stroke, circle as scircle } from "ol/style";

// 添加图层

import tilelayer from 'ol/layer/tile'

import {

 vector as vectorlayer} from 'ol/layer'

import {

 xyz,vector as vectorsource} from 'ol/source'

//引入样式文件

import "ol/ol.css"
export default {
  data() {

  return {
    map:null

    }

  },

  mounted() {

  this.init();

   this.setmarker();

  },

  methods: {

    init(){

       this.map=new map({

         target:'map',

         layers:[new tilelayer({

           source: new xyz({

               url:'https://wprd0{1-4}.is.autonavi.com/appmaptile?lang=zh_cn&size=1&style=7&x={x}&y={y}&z={z}',

           })

         })

         ],

        view:new view({


            // 将西安作为地图中心 

            // olproj.fromlonlat方法将经纬度转换成对应的坐标

          center:olproj.fromlonlat([108.945951, 34.465262]),

          zoom:2

        }),

       })

    },

    setmarker(){

        let _style = new style({

            image:new scircle({

                radius:10,

                stroke:new stroke({

                    color:"#fff",

                }),

                fill: new fill({

                    color:'#3399cc',

                }),

            }),

        });

        let _feature = new feature({

 

            geometry:new point(olproj.fromlonlat([108.945951, 34.465262])),

        });

        _feature.setstyle(_style);

        let _marker = new vectorlayer({


            source: new vectorsource({

               feature:[_feature],

            }),

        });

        this.map.addlayer(_marker);

    },

  },

}

</script>

<style scoped>

  #map{

      /* 屏幕宽高 */

    width: 100vw;

    height: 100vh;

  }

</style>
