ArcMap

Network Source

サマリー

Provides information about the network sources in the network dataset. Network sources can be of four types; edge sources, junction sources, turn sources, and system junction sources. Use the sourceType property to identify the type of network source.

Based on the type of the network source, the network source object can support additional properties specific to that source type. Edge sources and junction sources supports additonal properties along with the properties supported by the network source object. Turn sources and system junction sources do not support any additional properties.

Network Source Properties Example

Displays information for network sources in the network dataset..

# Name: NDSNetworkSourceProperties_ex01.py
# Description: Print the information about the network sources 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 ("------- Network sources") 

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

for source in sources:
    print ("%*s: %s" % (justify, "Source Name" , source.name)) 
    print ("%*s: %s" % (justify, "Source ID" , str(source.sourceID))) 
    print ("%*s: %s" % (justify, "Source Type", source.sourceType))
    print ("%*s: %s" % (justify, "Element Type", source.elementType))
    print (" ")
