erfamap

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

Map as generated by this tool

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.)

When not cache exists or forcing cache renewal, 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:

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