一般仅有少量数据会考虑该模式,大量数据会降低性能,优点是一次性将所有信特征信息传输到客户端,不用再次请求客户端,可以提高应用程序性能,规定任何一次快照模式只能返回不能超过1000个特征值,当然该值可以在ArcGIS server配置管理。
应该可以使用客户端方式或服务端方式对feature layer 进行属性、空间或者统计查询。被查询的feature layer 可以托管在ArcGIS Online或ArcGIS Enterprise上,或者也可以通过客户端进行创建。 服务端查询:feature layer 不并加载在地图上就可进行查询,可通过FeatureLayer对象的queryFeatures方法进行查询。 客户端查询:只有feature ...

Go to the Trails URL and browse the properties of the layer. Make note of the Name, Type, Drawing Info, and Fields properties. In CodePen, create a FeatureLayer and set the url property. Expand arcgisMap.addLayer(trailheadsLayer); // Trails feature layer (lines) const trailsLayer = new...

被过滤的feature layer 可以托管在ArcGIS Online或ArcGIS Enterprise上,或者也可以通过客户端进行创建。 服务端方式:通过给FeatureLayer对象的definitionExpression属性设置SQL表达式,就可进行服务端属性过滤,由服务端进行过滤计算之后将过滤结果返回给客户端显示,所以服务端过滤无需先将f eature layer 添加至地图上。
