上海市测绘院地图API加载库,通过该API库实现上海测绘院地图数据加载显示(仅限上海市徐汇行政服务中心政务网可用)
注意事项
由于smap-xh 属于新版本api,同时支持二三维一体化，目前功能还不完善，内容同步更新中。
目录
安装
npm install smap-xh --save使用
[以NPM包方式使用]
import SMap from 'smap-xh'
const map = new SMap.Map('container', {
viewMode: '3D',
center: [0, 0],
zoom: 5,
zooms: [1, 12],
pitch: 60,
mapStyle: 'smap://styles/dark', // 'smap://styles/normal' 'smap://styles/image'
showBuildingBlock: true
})[以普通JS方式使用]
<script src="http://10.201.37.225:8080/smiapi/smap/SMap.min.js">
const smap = new SMap.Map('mapcontainer', {
viewMode: '2D',

[生命周期]
[创建二维地图]

通上面方法一样，自定义性强，资源占用多，不宜多加[更新点状覆盖物多个updatefeature]
markone.icon.image = require('../assets/blue.gif')
markone.attributes['name'] = '点一更新'
marktwo.icon.image = require('../assets/blue.gif')
marktwo.attributes['name'] = '点二更新'
map.updatefeature([markone, marktwo])
