World Wind Java开发之十四——添加WMS地图服务资源

	public static WMSTiledImageLayer addTianDiTuImage() throws Exception
	{
		// 请求地图的URL
		String uri = "http://www.scgis.net.cn/imap/iMapServer/defaultRest/services/newtianditudom/WMS";
		// WMS
		WMSCapabilities caps;
		URI serverURI;
		serverURI = new URI(uri);
		// 获得WMSCapabilities对象
		caps = WMSCapabilities.retrieve(serverURI);
		// 解析WMSCapabilities数据
		caps.parse();

		// // 输出wms元数据信息
		// System.out.println(caps.getCapabilityInformation().toString());
		// 获取所有图层(这里只有一个，自己用geoserver发布的则可能有很多)
		final List<WMSLayerCapabilities> namedLayerCaps = caps.getNamedLayers();
		String layerName = null;
		for (WMSLayerCapabilities wmsLayerCapabilities : namedLayerCaps)
		{
			layerName = wmsLayerCapabilities.getName();
		}
		AVList params = new AVListImpl();
		// 图层的名称
		params.setValue(AVKey.LAYER_NAMES, layerName);
		// 地图服务的协议，这里是OGC:WMS
		params.setValue(AVKey.SERVICE_NAME, "OGC:WMS");
		// 获得地图的uri，也就是上面定义的uri
		params.setValue(AVKey.GET_MAP_URL, uri);
		// 在本地缓存文件的名称
		params.setValue(AVKey.DATA_CACHE_NAME, layerName);
		params.setValue(AVKey.TILE_URL_BUILDER,
				new WMSTiledImageLayer.URLBuilder(params));

		WMSTiledImageLayer layer = new WMSTiledImageLayer(caps, params);
		return layer;
	}

这里添加天地图影像作为底图，效果还是不错的，看下效果图：

另外，天地图还提供了在线注记底图服务，只需改动上面的地图请求地址即可，看下效果图：

这里加载的效果要比天地图的在线三维球的效果要好，有兴趣的可以去对比下。另外天地图的在线三维体验还是比较差的，只是单纯的浏览，单是这个体验效果还不是很好，毕竟这是政府的东东，不像Google财大气粗，全球几十万台服务器，天地图的商业化发展之路任重道远啊。

2、添加Geoserver发布的地图服务

3、WMS服务器管理面板
