ETS_VolumeOfPolygons

Volume of Polygons from TIN

Calculates the Volume and 3D Area of the polygons from the input polygon dataset based on user assigned level or different levels for each polygon from a field in the attribute table and the surface defined by a TIN. The Volume calculated for each polygon is split in two portions - above and below the surface.

Inputs:

Input Polygon feature dataset.
Output polygon dataset.
Reference TIN dataset.
A String - the field name of the input polygon attribute table to be used for levels of the polygons.
A Double - the level for all input polygons (optional).

Outputs:

New Polygon feature dataset.

Notes:

If the optional Level value is specified, it will be used for the calculations and the Level Field parameter will be ignored.
When the Level field is used, any features with NULL values in the field will be ignored and will not exist in the output.
The following new fields will be added to the output polygon feature dataset.
- ET_VAbove - Volume of the polygon above the surface.
- ET_VBelow - Volume of the polygon below the surface.
- ET_Area3D - 3D Area of the polygon.
- ET_Area - 2D Area of the polygon.
All attributes of the original polygons are preserved.

Parameters

Expression	Explanation
Function Name	PolygonVolumeTin
<input dataset>	A String representing the input polygon feature dataset.
<output dataset>	A String - the full name of the output polygon dataset.
<reference tin>	A String - the full name of the reference TIN dataset.
<level field>	A String indicating the field name of the input polygon attribute table to be used for levels of the polygons.
{Level}	A Double indicating the level for all input polygons (optional).

Running the function

ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETSurface\ETSRun.exe")

Language	Syntax
Python	subprocess.call([ETSPath, "PolygonVolumeTin", "input dataset", "output dataset", "reference tin", "level field", "level"])
.NET using ETSRun.exe	StartInfo.FileName = ETSPath StartInfo.Arguments = "PolygonVolumeTin" "input dataset" "output dataset" "reference tin" "level field" "level"
.NET using ETSOutX.dll	PolygonVolumeTin(input dataset, output dataset, reference tin, level field, level)
ArcPy	arcpy.PolygonVolumeTin("input dataset", "output dataset", "reference tin", "level field", "level")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
