@supermap/vue-iclient-mapboxgl入门,标记点、道路高亮显示

项目本来使用的是百度地图,但之后要放在内网,所以老大说要更换为超图,让我去研究。因为本人是菜鸟,而且网上关于超图的使用案例较少,所以我将其完整代码都放上了,希望能帮到你们一点小忙。

首先是按照官网的开发指南安装 | Vue-iClient-MapboxGL,按照步骤在main.js添加组件,但是启动时报出了异常,其中一个node_modules里文件代码段如下

return latOrLng
        ? {
            ...dms,
            direction: latOrLng === 'lat' ? (value > 0 ? 'N' : 'S') : value > 0 ? 'E' : 'W'
        }
        : dms;

这个问题我是去https://github.com/SuperMap/vue-iclient,降到了10.1.1后能正常使用。

之后是地图展示,这一步我是按照地图组件 | Vue-iClient-MapboxGL的加载iServe地图来展示地图。直接将该页面下的代码负责即可。代码如下:

<template>
  <sm-web-map :map-options="mapOptions"></sm-web-map>
</template>
<script>
export default {
  data() {
    return {
      mapOptions: {
        container: 'map', // container id
        style: {
          version: 8,
          sources: {
            'raster-tiles': {
              type: 'raster',
              tiles: [
                'https://iserver.supermap.io/iserver/services/map-china400/rest/maps/China/zxyTileImage.png?z={z}&x={x}&y={y}'
              ],
              tileSize: 256
            }
          },
          layers: [
            {
              id: 'simple-tiles',
              type: 'raster',
              source: 'raster-tiles',
              minzoom: 0,
              maxzoom: 22
            }
          ]
        },
        center: [120.143, 30.236], // starting position
        zoom: 3 // starting zoom
      }
    };
  }
};
</script>

地图可以展示后,还需要加一些标记点、道路高亮。此时就需要对其中mapOptions的style来进行操作。style中要标记点需要给sources和layers添加数据。

这时可以参考MapBoxgl的示例,我参考的是集合对象缓冲区分析

示例中加载点的代码如下(示例源码的85-111行)

 //加载点
        var pointGeometryFetures = [];
        for (i = 0; i < pointList.length; i++) {
            pointGeometryFetures.push({
                "type": "Feature",
                "geometry": {
                    "type": "Point",
                    "coordinates": pointList[i],
                }
            });
        }
        map.addLayer({
            "id": "bufferPoint",
            "type": "circle",
            "source": {
                "type": "geojson",
                "data": {
                    "type": "FeatureCollection",
                    "features": pointGeometryFetures
                }
            },
            "paint": {
                "circle-radius": 6, /* 圆的直径,单位像素 */
                "circle-color": "black", /* 圆的颜色 */
            },
            "filter": ["==", "$type", "Point"],
        });

 所以我将其手动添加到mapOptions的style中,添加完整个vue页面代码如下

<template>
  <sm-web-map :map-options="mapOptions"></sm-web-map>
</template>

<script>

export default {
  name: 'list',
  data () {
    return {
      mapOptions: {
        container: 'map', // container id
        style: {
          version: 8,
          sources: {
            'raster-tiles': {
              type: 'raster',
              tiles: [
                'https://iserver.supermap.io/iserver/services/map-jingjin/rest/maps/京津地区地图/zxyTileImage.png?z={z}&x={x}&y={y}'
              ],
              tileSize: 256
            },
            'geojson-test': {
              type: 'geojson',
              data: {
                type: 'Feature',
                geometry: {
                  type: 'LineString',
                  coordinates: [
