Network Analyst performance in Java ArcObjects vs Python

ArjunDongre — Fri, 13 May 2016 20:44:22 GMT

Does anybody have an experience in performing network analyst calculations in ArcObjects versus python? Does ArcObjects tend to run faster than Python? specifically running a Closest Facility Analysis and OD Cost Matrix Analysis.

Thanks!

Arjun

python doesn't actually 'do' anything, python access to the arcpy.na module provides access to the tools that are already in arctoolbox for example... Make Closest Facility Layer—Help | ArcGIS for Desktop so you can create a python script that imports the arcpy network analyst module, giving it access to the tool interface.... from there, I am sure you will find everything is a big wrapper around arcobjects code.

So consult What is the Network Analyst module?—Help | ArcGIS for Desktop

and you can explore the classes and functions available and you can even try to glean what is going on in the uncompiled (ie non-pyd or dll) in your installation directory,

Python access is good if you want to automate a network analyst workflow making modelbuild a complete waste of time if this is the route you are trying to go.

I may see if there is a difference in speed between solving on the MakeClosestFacilityLayer and directly running a findclosestfacility process.
