Welcome to the mfhrn_programs wiki!

Setup

  1. Ensure you have ArcGIS installed on your computer. (I have a Basic license.)
  2. Clone this repository onto your computer, in your local disk. Do NOT clone it into a network drive as this will run very slowly!
  3. Ensure you have access to a clean, up-to-date copy of the MHN.

I personally use the environment arcgispro-py3 which comes installed with ArcGIS.

Usage

The concept of this repository is that it reimagines mhn_programs (the original repository for processing the MHN) in a modern way which also acknowledges its role in freight and travel modeling. Essentially, this repository is designed to be the first step in a process which could later involve the MFN and MRN in later steps. See Paths for a visual of this logic.

Directory Structure

The input and script folder structures mirror each other. Ex. the input in input/1_travel will be processed by the scripts in scripts/1_travel.

images
input
`-- 1_travel
`-- 2_freight
scripts 
`-- 1_travel
`-- 2_freight
templates
  • images - this folder contains images which are shown in the README.md and the wiki.
  • input - this folder contains data which the programs use as input.
    • 1_travel (input) - this contains input which is specific to travel modeling and involves the MHN/MRN.
    • 2_freight (input) - this contains input which is specific to freight modeling and involves the MFN.
  • scripts - this folder contains scripts for running the programs.
    • 1_travel (scripts) - this contains scripts which are specific to travel modeling and involves information from the MHN/MRN.
    • 2_freight (scripts) - this contains scripts which are specific to freight modeling and involves information from the MFN.
  • templates - contains template input files.

After running the scripts, a folder called "output" will be created automatically. This will contain the output for the scripts.

My goal is to make things so simple that unless you're planning on modifying my scripts, you don't need to know anything at all about them to use them.
