Fence Diagram

Summary

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

Illustration

Fence Diagram

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.

Syntax

FenceDiagram_3d (in_line_features, in_surface, out_feature_class, {method}, {floor_height}, {ceiling_height}, {sample_distance})
ParameterExplanationData Type
in_line_features

The line features that will be used to construct the fence diagram.

Feature Layer
in_surface
[in_surface,...]

The surfaces that will be used to construct the fence diagram.

Mosaic Layer; Raster Layer; TIN Layer
out_feature_class

The output multipatch that is composed of vertical faces that depict the fence diagram.

Feature Class
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.

  • LINEARLinear interpolation will be used. This is the default.
  • NATURAL_NEIGHBORSNatural 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

Code sample

FenceDiagram example 1 (Python window)

The following sample demonstrates the use of this tool in the Python window.

arcpy.env.workspace = 'c:/data'
arcpy.ddd.FenceDiagram('fence_profile.shp', 
                       ['alluvium.tif', 'white_limestone.tif', 'yellow_limestone.tif'], 
                       'fence_diagram.shp', sample_distance='5 Meters')
