osmnx-color-roads

Quickly generate maps of road networks coloured by words in road names

What it does

• Gets the OSM graph for a given place
• Finds the most common words used in the graph
• Generates a colour scheme based on the common words
• Tries to ensure that the most common words have visually distinct colours
• Allows for stop words (TODO: Improve this system)
• Allows for a single line query to generate a map and allows for osmnx optional parameters, e.g. dpi, etc.

Installation

osmnx-color-roads requires osmnx which has a long list of dependencies. The fastest way to get started is to use conda to manage your Python environment and dependencies for osmnx.

1. Install conda
2. Setup osmnx with conda

   conda config --prepend channels conda-forge
   conda create -n ox --strict-channel-priority osmnx
   

3. conda activate ox
4. Download a copy of osmnx_color_roads.py from this repo
5. Run your python program that imports osmnx_color_roads

Warning: conda will clash with Pyenv - this StackOverflow can help

Example usage:

from  osmnx_color_roads import generate_image

generate_image('Oahu, Mililani, Honolulu County, Hawaii, United States of America', query_type='string', key_size=9, line_width=0.5)
