echarts地图下钻+平面3D效果+自定义toolTip+自定义立体数据图层

第一步： 先获取相关地图json文件，可以通过DataV.GeoAtlas地理小工具系列下载相关geoJson文件，对这些文件做好管理，如下getMap.js

javascript 复制代码 
import anyang from '@/assets/map/json/anyang.json'
import hebi from '@/assets/map/json/hebi.json'
import henan from '@/assets/map/json/henan.json'
import jiaozuo from '@/assets/map/json/jiaozuo.json'
import jiyuan from '@/assets/map/json/jiyuan.json'
import kaifeng from '@/assets/map/json/kaifeng.json'
import luohe from '@/assets/map/json/luohe.json'
import luoyang from '@/assets/map/json/luoyang.json'
import nanyang from '@/assets/map/json/nanyang.json'
import pingdingshan from '@/assets/map/json/pingdingshan.json'
import puyang from '@/assets/map/json/puyang.json'
import sanmenxia from '@/assets/map/json/sanmenxia.json'
import shangqiu from '@/assets/map/json/shangqiu.json'
import xinxiang from '@/assets/map/json/xinxiang.json'
import xinyang from '@/assets/map/json/xinyang.json'
import xuchang from '@/assets/map/json/xuchang.json'
import zhengzhou from '@/assets/map/json/zhengzhou.json'
import zhoukou from '@/assets/map/json/zhoukou.json'
import zhumadian from '@/assets/map/json/zhumadian.json'


const mapDict = {
  '周口市':'zhoukou',
  '漯河市':'luohe',
  '商丘市':'shangqiu',
  '许昌市':'xuchang',
  '洛阳市':'luoyang',
  '濮阳市':'puyang',
  '焦作市':'jiaozuo',
  '南阳市':'nanyang',
  '平顶山市':'pingdingshan',
  '新乡市':'xinxiang',
  '开封市':'kaifeng',
  '驻马店市':'zhumadian',
  '郑州市':'zhengzhou',
  '安阳市':'anyang',
  '鹤壁市':'hebi',
  '三门峡市':'sanmenxia',
  '信阳市':'xinyang',
  '济源市':'jiyuan',
}

const mapData = {
  henan,
  zhoukou,
  luohe,
  shangqiu,
  xuchang,
  luoyang,
  puyang,
  jiaozuo,
  nanyang,
  pingdingshan,
  xinxiang,
  kaifeng,
  zhumadian,
  zhengzhou,
  anyang,
  hebi,
  sanmenxia,
  xinyang,
  jiyuan,
}

export function getMap(mapName) {
    const cityName = mapDict[mapName]
    // console.log(cityName);
    if(cityName){
        // console.log('1111',cityName, mapData[cityName]);
        return [cityName, mapData[cityName]]

    }
    // if(!mapName){
    //   return ['henan', henan]
    // }
  return ['henan', henan]
}

**第二步：**导入到地图组件使用，通过下拉框或者点击地图获取name实现json切换

**第三步：**平面3D效果使用多个geo图层堆叠layoutCenter平移，下钻切换地图时记得注册地图registerMap

**第四步：**自定义toolTip比较简单，这里相关背景图使用import导入，关键点是自定义position位置（不自定义会出现安阳定在濮阳的情况），获取地图json中的centorid的坐标（这里的坐标自己可以直接修改位置），通过convertToPixel将地理坐标转换为屏幕坐标，相当好用

**第五步：**自定义立体图层，直接参考代码吧，网上也找过相关的参考，他们的实现方式是主体柱形部分采用左右多层次渐变的方式，要求上下渐变就不太合适。现在我这里这部分是公司里十年前端大佬手撸的，放心使用

**第六步：**地图emphsis鼠标移入使geo与series多图层联动触发，使用了鼠标移入移出事件，相关dispatchAction配置项在echarts官网查看
