TIN Polygon Volume (3D Analyst)

Available with 3D Analyst license.

Summary

Calculates the volumetric and surface area between polygons of an input feature class and a TIN surface.

Legacy:

This is a deprecated tool. This functionality has been added to the Polygon Volume tool.

Usage

• The input polygons and TIN need to overlap in horizontal extent in order for surface area or volume to be calculated.

Parameters

Label	Explanation	Data Type
Input TIN	The input TIN.	TIN Layer
Input Feature Class	The input polygon feature class.	Feature Layer
Height Field	The name of the field containing polygon reference plane heights.	String
Reference Plane (Optional)	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

Code sample

TINPolygonVolume example (Python window)

The following Python window script demonstrates how to use the TINPolygonVolume function in immediate mode.

import arcgisscripting
gp = arcgisscripting.create()

gp.workspace = "C:/data"
gp.TinPolygonVolume_3d("tin","PolyVol.shp", "Height", "ABOVE", "Volume", "S_Area")
