erfamap

Generate a map similar to https://www.ccc.de/regional from Wikidata and the doku.ccc.de Semantic MediaWiki data.

TL;DR

pip3 install -r requirements.txt
export DOKU_CCC_DE_BASICAUTH=username:password
./generate_map.py --update-erfalist

Installation

Create a Python virtualenv: python3 -m virtualenv venv
Enable the virtualenv: . venv/bin/activate
Install the dependencies: pip install -r requirements.txt

Instead of following these steps, you could also install the dependencies from your OS' package manager.

Usage

For a quick test run, point the script at the cache.example directory:

./generate_map.py --cache-directory cache.example

Find the result in the files map.svg and map.png.

If the wrong font is used in the PNG, make sure the chosen font is installed on your system. (CairoSVG does not support the use of @font-face in style sheets.)

Usually you'll want to keep the border cache, but renew the Erfa & Chaostreff list from time to time:

./generate_map.py --update-erfalist

For this, you need to provide the HTTP Basic Auth credentials to doku.ccc.de via an environment variable:

export DOKU_CCC_DE_BASICAUTH=username:password

A run without cache takes some time as it fetches all data from their sources:

Get a list of countries in Europe and federal states in Germany from Wikidata.
Download all these countries' and states' border shapes from Wikimedia Commons.
Get a list of Erfas & Chaostreffs from the doku.ccc.de Semantic Mediawiki API.
Resolve all POIs' (Erfas & Chaostreffs) street addresses' to geocoordinates using Nominatim.

Use the cache at least for the country and state borders. Otherwise, Wikidata will start rate limiting pretty quickly.
