地图数据的获取

声明

1. 之前提供的矢量地图数据来自第三方，由于部分数据不符合国家《测绘法》规定，BI发布版中不再打包提供地图数据
2. 由于行政区域是不断在变动的，离线地图文件很容易过期，对地图精度要求较高的用户请向相关权威部门申请地图数据
3. 离线区域地图从技术上来说仅仅为区块示意图，其目的为展示不同区块的数据强度，精准的边界线数据往往体积非常大，网络请求也会变慢，因此地图可视化过程中经常会用到轮廓数据精简手段 精简之后的轮廓数据，势必会有一些细节丢失，但这并不代表开发者、分析师、厂商的任何政治立场，请勿过渡解读
4. 如果用户对使用要求严格，请使用中国地图(经纬度地图/百度在线地图)，使用前通过在百度地图开发平台付费申请apikey

一些推荐地图信息获取地址, 以及下载配置：
github geoJson-cn (opens new window)

1. 下载geoJson-cn数据，拷贝mapdata文件夹到bi的user-files/ext文件夹
   
2. 更新区域索引：用管理员账号登录bi平台，在管理->图表配置->区域地图索引中填入ext/mapdata/area-code/index.json文件内容
3. 刷新页面即可生效
4. 关于地图数据相关的操作的详细说明请参考区域地图数据自定义

区域地图工作原理

原理

1. 地图绘制首先要有符合规范的地图数据用于绘制地图轮廓， IBI图形库ECharts使用GeoJson 格式的数据，具体格式见 (opens new window)
2. 有了地图轮廓绘制之后，第二步是把自己的数据映射到地图上去
3. 映射方式分为两种: 区域映射与经纬度映射。可以把地图轮廓想象为一个坐标系，
   • 区域映射以名称为坐标的一维坐标系
   • 经纬度映射以经纬度为坐标的二维坐标系
4. 百度在线地图，不需要准备地图数据，通过百度地图在线服务绘制地图轮廓，数据映射为经纬度映射

几种地图说明

地图类型	数据查询类型	映射方式
区域地图	聚合数据	区域名称
3D地图	聚合数据	区域名称，标线地图(区域名称或经纬)
3D地球	聚合数据	城市或国家名称
世界地图(也是一种区域地图)	聚合数据	国家名称
中国地图本地(经纬度地图)	明细数据	经纬度数据
中国地图(经纬度地图/百度在线地图)	明细数据	经纬度数据

区域地图

顾名思义区域地图是映射的地图的区块，在以区域名称为坐标的一维坐标系上，用户提供的数据名称和区块名称能对上号，则该名称对应的区域被点亮(视觉映射)，下图为默认的中国三级行政区域第一级区域

区域选择

• 区域选择，地图的区域可以选择，选定了区域之后，数据想要在地图上被正确映射就必须提供对应的区域数据

中国三级行政区域

一级区域为全国省级区、直辖市、自治区、特别行政区, 二级区域为地级市, 三级区域为区/县/县级市

图层级别选定

用户在选定地图数据之后，取消区域自适应勾选，可以选定固定的级别的区域

常见问题

Q: 我可以在一级中国雄鸡图上映射城市区域吗？
A: 不可以，一级地图的区块为省份，你可以自己准备一张按城市分割的地图数据，通过自定义区域地图，映射城市区域。 你还可以选择用经纬度地图，数据类型设置为城市，展示类型为散点实现需求

区域下钻

区域自适应用于地图下钻，要求有和区域地图级别对应的层级维度, 区域自适应勾选之后点击下钻操作，上一级数据被限定于点击的区域，改区域会用来自动改变地图图层

中国地图本地(经纬度地图)

区域选择

中国地图本地区域选择与区域地图所使用的地图数据(geo data)是相同的，不同的是区域地图映射到地图的区块，经纬度地图映射的是地图上的点或线(两个经纬度点连线)

数据配置

使用者需提供经纬度数据明细数据，数据不会做聚合操作，也就是明细数据。 考虑到用户的数据会出现经纬度组合一个字段、经纬度分开存储，我们也准备了相应的数据配置项应对；

数据配置

Q: 经纬度映射，数据配置里面有一个名称选项?
A: 我们内置了一套中国城市经纬度的字典，方便只有城市名称的情况下也能使用经纬度地图。使用城市名称做数据映射需要手工对数据进行聚合

中国地图(经纬度地图/百度在线地图)

该地图调用百度在线地图, 数据要求和上面的中国地图本地一致, 需要联网请求百度地图 API, 基于明细数据渲染(需自行申请百度开发者ak)

百度地图开发密钥获取流程: 点击这里 (opens new window)
注意:百度地图开发者密钥商用需要向百度公司缴费获取权限

设置开发者密钥

通过扩展配置，增加百度地图开发者调用

[
   [
    "script", {
      "src": "http://api.map.baidu.com/api?v=2.0&ak=xxxx"
    }
   ]
]

百度地图数据配置

数据配置与本地地图完全一致，经纬度映射，明细数据

使用BMap高阶开发

BMap为开发者提供了很多强大的图层样式控制API，百度地图开放平台JavaScript API v3.0 (opens new window), 在IBI平台上用户可以通过开发者模式，在afterSetOption函数中进行控制

afterSetOption = function(chart) {
    const map = chart.getModel().getComponent('bmap').getBMap();
    var top_left_control = new BMap.ScaleControl({anchor: BMAP_ANCHOR_TOP_LEFT});
    map.addControl(new BMap.NavigationControl());    
    map.addControl(new BMap.OverviewMapControl());   
}
