街道管理难题怎么破？高德地图“黑科技”给出完美答案！

高德开放平台2025-03-13 14:38

背景

本次分享的实战案例项目名为"智慧街道一体化平台"。由于开发时间紧迫，我采用了Vue2框架进行前后端架构开发，并基于高德地图的JS API和Web基础服务API，实现了一个简单的街道管理项目。客户需要可视化大屏展示，因此我们重点展示了街道社区在地图中的效果。

目标

客户关于街道可视化部分的主要需求包括：在地图上展示街道全貌，实现街道中社区的区域化展示效果；通过序号标注小区，并在点击标注点位时将地图视角定位并放大到对应社区；同时，在信息窗体中显示对应小区的相关信息。

方案设计

1、街道的边界区域化

为了实现对街道边界的区域化展示，我查阅了JS API文档，并采用了多边形AMap.Polygon功能。通过该功能，我们可以方便地绘制出街道的边界。

官方功能示意图

demo效果图

完整示例代码如下。

js 复制代码 
 
const streetCoordinates = [
            [
              [119.017987, 33.616876],
              [119.019426, 33.616761],
             此处省略我当时手动采集的街道边界的经纬度坐标点.....
            ],
          ];
          var HuaihaiPolyline = new AMap.Polyline({
            path: streetCoordinates,
            isOutline: true,
 outlineColor: "#D9251C",
            borderWeight: 3,
            strokeColor: "#D9251C",
            strokeOpacity: 1,
            strokeWeight: 6,
            // 折线样式还支持 'dashed'
             strokeStyle: "dashed",
            // strokeStyle是dashed时有效
            strokeDasharray: [15, 5],
            lineJoin: "round",
            lineCap: "round",
            zIndex: 50,
           strokeWeight: 1,
          });
          this.map.add([HuaihaiPolyline]);

2、社区范围的区域化显示

在该街道中共有7个社区。为了方便展示，我手动采集了社区的坐标点位，并通过不同色块展示了街道中的社区。

    polyEditor.open();

通过该demo网页手动画出覆盖物区域，最后点击获取经纬度数组按钮即可在浏览器控制台打印出来。

3、小区marker点采集

对于小区marker点的采集，我采用了管理员在平台添加小区时一并添加小区坐标点的方式。这样，无论后续新增多少小区，都可以由街道管理员自行添加或修改坐标点位。

具体解决方案是，管理员在新增小区的时候，先输入小区名称，通过点击查询小区坐标点，这里调用高德开放平台的POI高级搜索API功能，获取到小区的坐标点，最后点击创建即可。这里要非常感谢高德开放平台的web服务有每日免费额度，为我们开发者提供了便利。

通过POI服务获取小区坐标点demo的完整代码如下。

效果展示

通过接口获取marker点列表后，我为每个marker添加了点击事件。点击后，地图会定位并放大到对应位置。最终实现的网页效果如下所示。

最终我将网页中地图区域的内容完整的封装成了一个Vue组件，完整代码如下。
