smap-build v0.0.23
smap-xh
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',
center: [0, 0],
zoom: 5,
zooms: [1, 12],
mapStyle: 'smap://styles/dark', // 'smap://styles/normal' 'smap://styles/image'
})示例
地图
生命周期
创建二维地图
import SMap from 'smap-xh'
const map = new SMap.Map('container', {
center: [0, 0],
zoom: 5
})
创建三维地图
import SMap from 'smap-xh'
const map = new SMap.Map('container', {
viewMode: '3D',
center: [0, 0],
zoom: 4,
pitch:60
})
地图样式
地图样式-默认样式
const map = new SMap.Map('container', {
viewMode: '2D',
center: [0, 0],
zoom: 4,
mapStyle: 'smap://styles/normal' //为赋值时候，默认为smap://styles/normal
})地图样式-暗色样式
const map = new SMap.Map('container', {
viewMode: '2D',
center: [0, 0],
zoom: 4,
mapStyle: 'smap://styles/dark'
})地图样式-实景样式
const map = new SMap.Map('container', {
viewMode: '2D',
center: [0, 0],
zoom: 4,
mapStyle: 'smap://styles/image'
})地图属性
地图缩放级别zooms控制
const map = new SMap.Map('container', {
center: [0, 0],
zoom: 5,
zooms: [1, 9] //二三维都支持,默认最新小0，最大10 建议二维默认设置最小1，最大9
})地图是否可旋转
const map = new SMap.Map('container', {
center: [0, 0],
zoom: 5,
zooms: [1, 9]
rotateEnable: false //暂二维支持
})三维建筑地块是否可见
const map = new SMap.Map('container', {
center: [0, 0],
zoom: 5,
zooms: [1, 9]
showBuildingBlock: false, //三维地图可用,未赋值时候默认为true
})获取三维地图俯仰角
const pitch= map.getPitch()设置三维地图俯仰角
map.setPitch(30)获取地图中心点
const mapcenter = map.getCenter()获取地图级别
const zoom = map.getZoom()设置地图中心点
//2D

//2D
map.setZoomAndCenter(10，[0, 0])
//3D
map.setZoomAndCenter(10，[0, 0, 0])获取地图比例尺
map.getScale()设置地图旋转角度
map.setRotation(90)获取地图显示范围
const bounds = map.getBounds()设置地图显示范围
//2D
const mybounds = new SMap.Bounds([-12244.941157, -6531.252646], [13155.109644,5811.584540]);

map.setBounds(mybounds);地图平移-像素平移
map.panBy(50, 100)地图平移-中心点平移
//2D
map.panTo(0, 0)
//3D
map.panTo(0, 0, 0) OR map.panTo(0, 0)地图放大
map.zoomIn()地图缩小
map.zoomOut()设置地图样式
map.setMapStyle('smap://styles/normal')获取地图样式
map.getMapStyle()开启穿透地表

此方法适合加载大量数据点二维10万个点展示
二维10万个点聚合展示
三维10万个点展示
三维10万个优化显示
更新点状覆盖物组updatefeature
massmarksgroup.overlayers[0].attributes['name'] = '点5更新'
massmarksgroup.overlayers[0].attributes['style'] = '1'
massmarksgroup.overlayers[1].attributes['style'] = '0'
map.updatefeature(massmarksgroup)删除点状覆盖物组removefeature
map.removefeature(massmarksgroup)地图事件
