+# ccc maps
+
+the [svg map] used on [ccc de] is at least potentially outdated
+and thus should be updated automically
+
+[svg map]: https://chaos.expert/telegnom/erfakarte 
+[ccc de]: https://www.ccc.de/regional
+
+## process
+
+1. fetch addressed of a convenient source
+2. resolve geo coordinates for addresses, e. g. `geopy`[0]
+3. visualize on a map, e. g. `leaflet.js`[1]
+
+## data
+
+the address data source is the semantic [documentation wiki], queried with [result format]
+
+[documentation wiki]: https://doku.ccc.de/Liste_der_Erfa-Kreise_und_Chaostreffs
+[result format]: https://www.semantic-mediawiki.org/wiki/Help:CSV_format
