TIN Polygon Tag

Summary

Creates polygon features using tag values in a triangulated irregular network (TIN) dataset.

Illustration

Usage

  • Tag values can be assigned using an integer field in a polygon feature class by loading the polygon into the TIN as a valuefill surface type.

  • Triangles that do not have a tag explicitly defined are assigned the default value of 0.

  • All contiguous triangles with an identical tag value will be stored in a single polygon feature.

  • The tag value will be denoted as an attribute in the output feature class.

Syntax

TinPolygonTag_3d (in_tin, out_feature_class, {tag_field})
ParameterExplanationData Type
in_tin

The TIN dataset to process.

TIN Layer
out_feature_class

The feature class that will be produced by this tool.

Feature Class
tag_field
(Optional)

The name of the field storing the tag attribute in the output feature class. The default field name is Tag_Value.

String

Code sample

TinPolygonTag example 1 (Python window)

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

arcpy.env.workspace = "C:/data"
arcpy.TinPolygonTag_3d("tin", "tin_polytag.shp", tag_field="LanduseCode")
TinPolygonTag example 2 (stand-alone script)

The following sample demonstrates the use of this tool in a stand-alone Python script.

'''****************************************************************************
Name: TinPolygonTag Example
Description: This script demonstrates use of the 
             TinPolygonTag tool to extract tag information 
             from each TIN in the target workspace.
****************************************************************************'''
# Import system modules
import arcpy

# Set environment settings
arcpy.env.workspace = "C:/data"

# Set Local Variables
TagField = "Code"

# Create list of TINs
TINList = arcpy.ListDatasets("*", "Tin")

# Verify the presence of TINs in the list
if TINList:
    # Iterate through the list of TINs
    for dataset in TINList:
        # Define the name of the output file
        Output = dataset + "_domain.shp"
        # Execute TinPolygonTag
        arcpy.TinPolygonTag_3d(dataset, Output, TagFieldField)
    print("Finished.")
else:
    print("No TIN files reside in {0}".format(env.workspace))
