TIN properties

Zusammenfassung

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".

Eigenschaften

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

Codebeispiel

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)
