  • 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
