Is there some reason to record and upload tracks in well mapped areas? Can such data help anyone? The cost of doing this is quite low, on the other hand filling the database with useless data does not have much sense... |

If you have lots of traces, you can take an average of them to draw ways more accurately. There are many areas in OSM that appear to be "well mapped", but the roads are not actually that accurate. Plus having loads of traces can be useful for checking the alignment of aerial imagery. Though there are problems with using traces uploaded by others, as you don't know how accurate they are. Or whether they are actually following the road, or on a path alongside. If the traces were tagged in some way this might help, but most traces are not tagged in a consistent or useful way. So its usually best just to use traces you have recorded yourself, and are confident about. So overall, I would say it is worth having some traces for an area. Though probably pointless to upload hundreds of traces for a single road. good point about on road or path so I'll split my traces and tag the walk separate to drive there

Before uploading a trace, or maybe bit of trace,we could open an editor of map and have a look at how many traces it as already then make the decision on what needs a trace or what to trim from trace before uploading |
