TIN properties
Summary
The Describe function returns the following properties for TINs. Dataset Properties are also supported.
A TIN returns a dataType of "Tin".
Properties
Property | Explanation | Data Type |
fields (Read Only) |
A Python List containing Field objects for the TIN dataset | Object |
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
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
