cesium 之图层管理器篇（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 实现图层管理器效果
2.源代码 demo 下载

本篇实现 cesium 图层管理器功能，效果图如下：

• 图层配置文件信息

/*地图图层菜单目录构造*/
/*
*name-图层名称
*layerurl-图层服务配置
*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(WMS);
6 代表kml,kmz;
7 代表geoJson;
*layerid-图层id
*/
