TIN properties

Résumé

The Describe function returns the following properties for TINs. Dataset Properties are also supported.

A TIN returns a dataType of "Tin".

Propriétés

Propriété	Explication	Type de données
fields (Lecture seule)	A Python List containing Field objects for the TIN dataset	Field
hasEdgeTagValues (Lecture seule)	Indicates whether the TIN dataset has edge tag values	Boolean
hasNodeTagValues (Lecture seule)	Indicates whether the TIN dataset has node tag values	Boolean
hasTriangleTagValues (Lecture seule)	Indicates whether the TIN dataset has triangle tag values	Boolean
isDelaunay (Lecture seule)	Indicates whether the TIN dataset was constructed using Delaunay triangulation	Boolean
ZFactor (Lecture seule)	Multiplication factor applied to all z-values in a TIN to provide unit congruency between coordinate components	Integer

Exemple de code

TIN properties example (stand-alone script)

The following stand-alone script displays properties for a TIN. It also prints all the field names for the TIN.

import arcpy

# Create a Describe object
#
desc = arcpy.Describe("C:/data/antelope_island")

# Print TIN properties
print("%-21s %s" % ("HasEdgeTagValues:", desc.hasEdgeTagValues))
print("%-21s %s" % ("HasNodeTagValues:", desc.hasNodeTagValues))
print("%-21s %s" % ("HasTriangleTagValues:", desc.hasTriangleTagValues))
print("%-21s %s" % ("IsDelaunay:", desc.isDelaunay))
print("%-21s %s" % ("ZFactor:", desc.ZFactor))

# Print the field names in the TIN
print("\nFields in the TIN:")
for field in desc.fields:
    print("\t%s" % field.name)
