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))
print(" ")
