Label | Explanation | Data Type |
Input TIN | The TIN dataset that will be processed. | TIN Layer |
Output Feature Class | The feature class that will be produced. | Feature Class |
Tag Value Field (Optional) | The name of the field storing the tag attribute in the output feature class. The default field name is Tag_Value. | String |
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.
Parameters
arcpy.ddd.TinPolygonTag(in_tin, out_feature_class, {tag_field})
Name | Explanation | Data Type |
in_tin | The TIN dataset that will be processed. | TIN Layer |
out_feature_class | The feature class that will be produced. | 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
The following sample demonstrates the use of this tool in the Python window:
arcpy.env.workspace = "C:/data"
arcpy.ddd.TinPolygonTag("tin", "tin_polytag.shp", tag_field="LanduseCode")
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.
