cesium 之地图切换展示效果篇(附源码下载)

前言

cesium 官网的api文档介绍地址cesium官网api,里面详细的介绍 cesium 各个类的介绍,还有就是在线例子:cesium 官网在线例子,这个也是学习 cesium 的好素材。

内容概览

1.基于cesium 实现地图切换展示效果
2.源代码 demo 下载

本篇实现 cesium 地图切换展示功能,效果图如下:

实现思路

  • 配置不同类型地图服务
MapConfig.mapInitParams = {
extent: {//初始化范围


xmin: 12445986.749812808,


ymin: 2460330.5958780753,


xmax: 12450572.971510038,


ymax: 2462313.1812992743


},


spatialReference: {//地图空间参考坐标系


wkid: 3857


},


/*备注说明:配置底图列表


*type代表地图服务类型(0代表ArcGisMapServerImageryProvider;1代表createOpenStreetMapImageryProvider;


2代表WebMapTileServiceImageryProvider;3代表createTileMapServiceImageryProvider;


4 代表UrlTemplateImageryProvider;5 代表WebMapServiceImageryProviderr)


*proxyUrl代理请求服务


*iconUrl图标


*name显示名称


*Url地图Url

imageryViewModels:[

}
  • 初始化调用
//底图切换
cesium.loadSwitcherMap(MapConfig.mapInitParams.imageryViewModels);

 

  • 地图切换核心部分代码
