Polygon Volume (3D Analyst)

Summary

Calculates the volume and surface area between a polygon of a constant height and a surface.

Usage

  • Calculations will only be made for the portions of the input polygons and the TIN or terrain dataset surface that overlap.

  • Each polygon boundary is first intersected with the interpolation zone of the surface. This identifies the area in common between the two. Then, volume and surface area are calculated for all triangles and portions thereof that fall within the intersected polygon.

  • The volume represents the region between the surface and the space above or below the polygon features based on the selection made in the Reference Plane parameter:

    • Calculate above the plane—Volume is calculated between the plane and the underside of the surface.
    • Calculate below the plane—Volume is calculated between the plane and the topside of the surface. The surface area for the same portion of the surface is also calculated.

Parameters

LabelExplanationData Type
Input Surface

The TIN, terrain, or LAS dataset surface to process.

LAS Dataset Layer; Terrain Layer; TIN Layer
Input Features

The polygon features that define the region being processed.

Feature Layer
Height Field

The field in the polygon's attribute table that defines the height of the reference plane used in determining volumetric calculations.

String
Reference Plane
(Optional)

The direction from the reference plane that volume and surface area will be calculated.

  • Calculate above the plane —Volume and surface area are calculated above the reference plane height of the polygons.
  • Calculate below the plane —Volume and surface area are calculated below the reference plane height of the polygons. This is the default.
String
Volume Field
(Optional)

Specifies the name of the field that will contain volumetric calculations. The default is Volume.

String
Surface Area Field
(Optional)

Specifies the name of the field that will contain the surface area calculations. The default is SArea.

String
Pyramid Level Resolution
(Optional)

The z-tolerance or window-size resolution of the terrain pyramid level that will be used. The default is 0, or full resolution.

Double
