TIN properties

Resumen

The Describe function returns the following properties for TINs. The Dataset property group is also supported.

For a TIN, the Describe dataType property returns a value of "Tin".

Propiedades

Propiedad	Explicación	Tipo de datos
fields (Sólo lectura)	A list containing Field objects for the TIN dataset.	Field
hasEdgeTagValues (Sólo lectura)	Indicates whether the TIN dataset has edge tag values.	Boolean
hasNodeTagValues (Sólo lectura)	Indicates whether the TIN dataset has node tag values.	Boolean
hasTriangleTagValues (Sólo lectura)	Indicates whether the TIN dataset has triangle tag values.	Boolean
isDelaunay (Sólo lectura)	Indicates whether the TIN dataset was constructed using Delaunay triangulation.	Boolean
ZFactor (Sólo lectura)	Multiplication factor applied to all z-values in a TIN to provide unit congruency between coordinate components.	Integer

TIN properties example

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)
