System Junction Source Properties Example

Displays information for system junction sources in the network dataset.

# Name: NDSSystemJunctionSourceProperties_ex01.py
# Description: Print the information about the system junction sources 
#              defined for the network dataset

import arcpy
import sys

# Set workspace
arcpy.env.workspace = "C:/Data/SanFrancisco.gdb/Transportation"

#Create a Describe object from the network dataset
desc = arcpy.Describe("Streets_ND")

justify = 35
print ("------- System junction source")

#SDC network datasets do not have system junction source.
networktype = desc.networkType 
if networktype.lower() == "sdc": 
    print ("%*s" % (justify, "(No system junction source)")) 
    sys.exit(0)

#Get the system junction source for the network dataset.
sjSource = desc.systemJunctionSource 
if not sjSource: 
    print ("%*s" % (justify, "(No system junction sources)")) 
    sys.exit(0) 

print ("%*s: %s" % (justify, "Source Name" , sjSource.name)) 
print ("%*s: %s" % (justify, "Source ID" , str(sjSource.sourceID))) 
print ("%*s: %s" % (justify, "Source Type", sjSource.sourceType))
print ("%*s: %s" % (justify, "Element Type", sjSource.elementType))
print (" %*s: %s" % (justify, "Elevation Field",sjSource.elevationFieldName))
