最近工作需要做三维GIS相关的开发，因此接触了Cesium，采用的Web容器是Tomcat，地图服务由Geoserver发布同时也调用了在线地形服务。Tomcat和Geoserver的安装部署再次就不再重复介绍。安装完Tomcat之后，将下载的Geoserver和Cesium都放在Tomcat安装目录的webapp目录下
启动Tomcat之后就可以访问，本文所采用的IDE是WebStorm，在WebStorm中打开在Tomcat中部署好的Cesium工程，在Apps目录下新建一个HellWorld.html,输入以下代码

<div id="cesiumContainer"></div>
<script>
// var viewer = new Cesium.Viewer('cesiumContainer');
var terrainProvider=new Cesium.CesiumTerrainProvider({
url:"https://assets02.agi.com/stk-terrain/world"
});
var viewer=new Cesium.Viewer("cesiumContainer",{
timeline:false,
animation:false,//去除时间线条和Animation widget;
baseLayerPicker:false,
terrainProvider:terrainProvider
});
var layers=viewer.imageryLayers;
layers.addImageryProvider(new Cesium.WebMapServiceImageryProvider({
url:'http://localhost:8080/geoserver/workspace/wms',
layers:'workspace:geotiff_coverage',
parameters : {
format : 'image/png',
transparent : true,
service : 'WMS',
version : '1.1.0',
request : 'GetMap'
}
}));
viewer._cesiumWidget._creditContainer.style.display="none";
</script>
</body>
</html>
最后在球上显示的结果就是一部分贴有影像纹理的三维地形：
