最近在进行地图符号的三维配置,在尝试三维符号时,发现无论如何都无法出现地下的效果,很郁闷,终于在好闺蜜的帮助下了解到了关于数据和服务的z值
z 值通常表示可用于以三维形式显示要素的高程或高度。要素的各折点可将 z 值与 x,y 位置信息一同存储。虽然 ArcMap 及其编辑环境是二维的,但仍可以输入、编辑和维护 z 值。
在 ArcMap 中执行编辑操作时,z 值的分配由编辑工具或命令所执行的常规功能决定:是创建新要素还是编辑现有要素。所创建的、用于生成新要素的大多数操作都会为所有折点分配相同的默认 z 值。修改现有要素时,将内插新的 z 值,并将更新后的值分配给已编辑的折点。但是,某些编辑操作只会维护现有 z 值。
在catalog中新建shp或要素类,命名选择类型并勾选“坐标将包含z值”。
在属性表中添加字段,并赋值(示例中由于点位于地下,所以z赋值负值,若在地上则赋值正值)
打开工具箱<<数据管理工具<<要素<<调整3D的z值
这样,就可以得到包含z值的数据了,三维效果也就可以展示啦

效果如下:
