Relation Analyzer
The Relation Analyzer analyzes OSM relations for gaps. This is useful for all kinds of routes, including routes that are currently being surveyed. On the European continent alone there are more than 70,000 relations (May 2009). During general editing processes relations often get destroyed by unexperienced users. The Relation Analyzer is useful for keeping an eye on a relation and immediately helps you to identify errors.
At the same time you can extract a relation as a GPX or KML file for your GPS device or view it directly in the OSM map. The export for navigation only makes sense if the relation is in one piece. Additionally it supports the JOSM RemoteControl Plugin, so you can find and fix the relation gaps (bugs) right away! Use the search function to find a relation by name.
You can try the software at http://ra.osmsurround.org/. The current version uses the latest (0.6) OSM API.
For known cycle routes in Germany check WikiProject_Germany/Radfernwege. There you can find already defined relation Ids.
