After I add names to streets and add some POIs in the past, I have done my first real logging and making a map today. It's really easy with JOSM to create maps, I have thought it would be more difficult. You can have a look at the result at the map link (the data are online, should be rendered the next few minutes/hours from t@h out there or from my own t@h client here ;) ). It's just a small park with the belonging footways. But it's a start. Maybe there will be some more streets, footways, POIs, etc. next weekend for Graben-Neudorf.
