图层(Layer)是地图上用于组织和管理要素的容器。它负责渲染和显示要素,并控制要素的样式、可见性、顺序等。图层可以分为多种类型,每种类型适用于不同的用途。 常见的图层类型: 矢量图层(Vector Layer):用于显示矢量要素(如点、线、面)。 栅格图层(Tile Layer 或 Image Layer):用于显示栅格数据,如卫星影像、地图...
应用能够使用不同的样式展示feature layer 以增加数据的可视化。第一步是选择合适的renderer。SimpleRenderer提供相同的符号渲染所有的要素,UniqueValueRenderer能根据属性不同值提供不同的符号渲染要素(唯一值渲染),ClassBreaksRenderer能根据属性不同范围值提供不能的符号渲染(范围值渲染)。在绘制feature layer时Renderers负...
动态地图服务主要用于地图的展示,其还有一个不足,即它不允许用户与地图的子图层进行交互,不能遍历得到每个图层,也不能查询图层。这里使用要素图层(Feature Layer)来代替它。 Feature Layer可以访问每个空间要素及其属性,可以将其看成是ArcMap中的要素类(Feature Class),它可以接受用户的查询. 1.配置ArcMap、ArcGIS S...
