Yes! The user importing the track data in our system is responsible for selecting only those records that make up a way. If this is not convenient he can leave the track in the background and not at all use the data directly but create the way manually in a click, click, click,... manner. We can also provide functonlity in out app to first specifiy an existing (start) node and then do the click, click, click ... thing so that the newly created way has a defined binding to the existing street data. Thus the data we are producing is already of high value (could directly be inserted into the public OSM database). >> • our users cannot use the official OSM editor for several reasons (to >> complicated, no direct access to our tracks,...) > > Depending on your Java expertise, you could program some JOSM plugin. > Just an idea, though.

No problem there. Wow, I believe that's whatI was looking for!! Scanning this page ...
