百度地图实现增加打点mark自定义图标自定义地图样式-运动轨迹

需求背景

1、查看某个地区所有业务员的坐标
2、点击业务员坐标可展示具体信息、当前具体地址
3、点击某个业务员名字,自动关联到地图上的位置
4、查看业务员当天的行程轨迹
5、动态切换地图上坐标的自定义图标
6、支持展示所有业务员在可视区内(自适应缩放地图比例,展示所有业务员位置)

之所以没有选择用 vue-baidu-map,是因为有 bug。。。


如果你之前没有接触过地图方面的开发,建议先去官网熟悉一下 api。
百度地图 API(javascript API)
具体的参考类
大概会用到以下几个 api:

  1. 账号和秘钥获取
  2. 初始化地图
  3. 自定义地图样式
  4. 添加控件
  5. 添加标注
  6. 添加信息窗口
  7. 地图事件处理
  8. 出行路线规划
  9. 坐标系之间的转换

先看一下最终的效果图

显示轨迹的模块

项目是 vue 项目 我贴一下 map.vue 的文件代码
html 代码????
只需要一个显示地图的 div

<template>
    <div class="main">
        <div id="container" class="bm-view">
        </div>
        <div class="btn__group">
            <button @click="changeType('all')" :class="{'active': item ==='all'}"> 全部 </button>
            <button @click="changeType('path')" :class="{'active': item ==='path'}"
                v-show="currentItem==='car'"> 轨迹 </button>
        </div>
    </div>
</template>

js 部分????

<script>

绘制轨迹的方法????

export const drawTrack = (map, arr, name) => {
    // 先清空之前的 marker
    map.clearOverlays();
    let driving = new BMap.DrivingRoute(map); // 创建轨迹实例 
    // 生成坐标点
    let trackPoint = arr.map(v => new BMap.Point(''+ v.lng,'' + v.lat))
    for (let i = 0, len = trackPoint.length; i < len; i++) {if (i != trackPoint.length - 1) {driving.search(trackPoint[i], trackPoint[i + 1]);
        }
    }
    // icon 的参数
    let size = new BMap.Size(28, 32),
        offset = new BMap.Size(0, -13),
        imageSize = new BMap.Size(28, 32),
        icon = new BMap.Icon("/static/car.png", size, {imageSize: imageSize});

    driving.setSearchCompleteCallback(() => {let pts = driving.getResults().getPlan(0).getRoute(0)
            .getPath(); // 通过轨迹实例,获得一系列点的数组  
        let polyline = new BMap.Polyline(pts, {
            strokeColor: '#00bebebe',
            strokeOpacity: 1,
        });
        map.addOverlay(polyline);
        let labStyle = {
            minWidth: '28px',
            height: '28px',

            fontSize: '12px',
            backgroundColor: 'none',
            border: '1px solid #00bebebe',
            borderRadius: '4px',

        }
        // 画图标、想要展示的起点终点途经点
        for (let i = 0, len = trackPoint.length; i < len; i++) {let marker = new BMap.Marker(trackPoint[i], {
                icon: icon,
                offset: offset
            });

            let lab,
            nameLab;
            if (i == 0) {
                lab = new BMap.Label("起点", {position: trackPoint[i]
                });
                lab.setStyle(labStyle)
            } else if (i == trackPoint.length - 1) {
                lab = new BMap.Label("终点", {position: trackPoint[i]
                });
                lab.setStyle(labStyle)
                // 添加一个名字 label
                nameLab = new BMap.Label(name, {offset:new BMap.Size(0,-30),
                    position: trackPoint[i]
                })
                nameLab.setStyle(labStyle)
            } 
            map.addOverlay(lab);
            map.addOverlay(nameLab);
        }
        map.setViewport(trackPoint);
    });

css 样式代码我就不贴出来了,你们随意发挥~

注意的问题点如下????

  • 地图容器的 div 一定要设置宽高,不然地图显示不出来
  • 确认拿到的坐标系。如果是其他坐标系,需要转为百度地图的坐标系,否则显示的位置会有偏差,坐标系的转换我上面已经贴了链接,目前国内主要有以下三种坐标系:
    WGS84:为一种大地坐标系,也是目前广泛使用的 GPS 全球卫星定位系统使用的坐标系。

    GCJ02:又称火星坐标系,是由中国国家测绘局制订的地理信息系统的坐标系统。由 WGS84 坐标系经加密后的坐标系。

    BD09:为百度坐标系,在 GCJ02 坐标系基础上再次加密。其中 bd09ll 表示百度经纬度坐标,bd09mc 表示百度墨卡托米制坐标。

    非中国地区地图,服务坐标统一使用 WGS84 坐标。
    百度对外接口的坐标系为 BD09 坐标系,并不是 GPS 采集的真实经纬度,在使用百度地图 JavaScript API 服务前,需先将非百度坐标通过坐标转换接口转换成百度坐标。

  • 特别注意的是,保证每个坐标数组都是转成百度地图坐标之后的值,这个很关键。
    • *
