程序喵描述：此示例显示了如何添加一个的地形底图层到您的应用程序。该示例使用一个缓存的地图服务从ArcGIS Online。您可以浏览ArcGIS.com额外的在线参考底图和地图服务的网站，或使用ArcGIS Server作为服务发布自己的地理数据。
此示例设置初始范围的地图在旧金山的区域，使用下面的代码：
var initExtent=new esri.geometry.Extent({"xmin":-13635568.034589134,"ymin":4541606.359162286,"xmax":-13625430.573712826,"ymax":4547310.472398059,"spatialReference":{"wkid":102100}});
map = new esri.Map("map",{extent:initExtent});演示地址联接：http://help.arcgis.com/en/webapi/javascript/arcgis/samples/map_topo/index.html
