操作方法
高程点表示地表的高度,每个点都包含地球表面的 x,y,z 测量值。 可以使用高程点作为输入来计算区域的体积,结果将提供从特定深度的土地挖掘一定区域收集的土壤量等信息。可以通过以下步骤从高程点计算区域的体积:首先从高程点插值生成栅格表面,然后运行“表面体积”工具来计算该区域高于或低于特定高程(参考平面)的体积。
Note: The 3D Analyst extension must be licensed to perform the workflows described in this article.
所提供的说明描述了如何从高程点计算区域的体积。

Note: There are several interpolation methods available in ArcGIS Desktop depending on the purpose of the raster interpolation. For more information on other raster interpolation methods, refer to An introduction to interpolation methods.

Note: In this scenario, the boundary feature class represents the area of interest, not the entirety of the interpolated area.
