TIN Polygon Volume (3D Analyst)
摘要
Calculates the volumetric and surface area between polygons of an input feature class and a TIN surface.
旧版本：This is a deprecated tool. To learn more about how this tool works click here to view archived documentation. This functionality has been added to the Polygon Volume tool.
用法
-
The input polygons and TIN need to overlap in horizontal extent in order for surface area or volume to be calculated.
语法
| 参数 | 说明 | 数据类型 |
in_tin |
The input TIN. | TIN Layer |
in_feature_class |
The input polygon feature class. | Feature Layer |
in_height_field |
The name of the field containing polygon reference plane heights. | String |
reference_plane （可选） |
The keyword used to indicate whether volume and surface area are calculated ABOVE the reference plane height of the polygons, or BELOW. The default is BELOW. | String |
out_volume_field （可选） |
The name of the output field used to store the volume result. The default is Volume. | String |
surface_area_field （可选） |
The name of the output field used to store the surface area result. The default is SArea. | String |
代码示例
The following Python Window script demonstrates how to use the TIN Polygon Volume function in immediate mode.
import arcgisscripting
gp = arcgisscripting.create()
gp.CheckOutExtension("3D")
gp.workspace = "C:/data"
gp.TinPolygonVolume_3d("tin","PolyVol.shp", "Height", "ABOVE", "Volume", "S_Area")
