Summary
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".
Properties
| Property | Explanation | Data Type |
| fields (Read Only) | A list containing Field objects for the TIN dataset. | Field |
| hasEdgeTagValues (Read Only) | Indicates whether the TIN dataset has edge tag values. | Boolean |
| hasNodeTagValues (Read Only) | Indicates whether the TIN dataset has node tag values. | Boolean |
| hasTriangleTagValues (Read Only) | Indicates whether the TIN dataset has triangle tag values. | Boolean |
| isDelaunay (Read Only) | Indicates whether the TIN dataset was constructed using Delaunay triangulation. | Boolean |
| ZFactor (Read Only) | Multiplication factor applied to all z-values in a TIN to provide unit congruency between coordinate components. | Integer |
Code sample
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)
