Fence Diagram (3D Analyst)

Summary

Constructs a vertical cross-section of a collection of surfaces.

Illustration

Usage

• A fence diagram provides a useful way to visualize the space between multiple overlapping surfaces in 3D space, such as stratigraphic data.

• Bilinear interpolation will be used to derive the height along a raster surface. For TIN surfaces, natural neighbor and linear interpolation options can be specified.

• A table of the x,y,z-values in the fence diagram can be generated with the Stack Profile tool.

Parameters

Label	Explanation	Data Type
Input Line Features	The line features that will be used to construct the fence diagram.	Feature Layer
Input Surface	The surfaces that will be used to construct the fence diagram.	Mosaic Layer; Raster Layer; TIN Layer
Output Multipatch Feature Class	The output multipatch that is composed of vertical faces that depict the fence diagram.	Feature Class
Interpolation Method (Optional)	The interpolation method that will be used to obtain z-values from TIN surfaces when constructing the fence diagram. This parameter does not apply to raster surfaces. Linear—Linear interpolation will be used. This is the default. Natural Neighbors—Natural neighbors interpolation will be used.	String
Floor Height (Optional)	A constant height used to define the lowest height of the fence diagram.	Linear Unit
Ceiling Height (Optional)	A constant height used to define the highest height of the fence diagram.	Linear Unit
Sample Distance (Optional)	The horizontal distance used for determining the positions where height measurements are interpolated from the underlying surfaces.	Linear Unit
