Resumen
The Describe function returns the following properties for TINs. Dataset Properties are also supported.
A TIN returns a dataType of "Tin".
Propiedades
Propiedad | Explicación | Tipo de datos |
fields (Sólo lectura) | A Python 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 |

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)
