This would be an interesting thing to try.<br><br>AFAIK its relatively easy to add a new layer to the t@h infrastructure and Osmarender could easily be adapted to render points from GPX files (perhaps using a pre-processor to convert GPX elements to OSM format nodes and ways). I do wonder, however, whether the t@h infrastrcuture is overkill, just for rendering tracklogs on a map.<br>
<br>It's not likely to be something that I'd have the time to tackle in the near future, but I'd certainly be willing to provide advice and guidance if someone else wanted to try to do it.<br><br>Generally, the GPX track logs don't get a lot of visibility at the moment, but its actually a very important part of the OSM project. It's one of our primary sources and as such we should be taking a lot more care about preserving them. <br>
<br>In particular, its very easy for JOSM users to trace from GPX files but then never upload them. In the past I've banged on about the importance of people identifying the source of their contributions. If the source is a track log then it really ought to be compulsory to upload that track log, otherwise we have no way of knowing that the data wasn't derived from some copyright source.<br>
<br>(It's pretty easy to tell if something has been traced from Yahoo! because the tracks line up very precisely, although tagging the source as Yahoo! is still helpful).<br><br>As the project grows we will need to be more vigilant about the provenance of contributions, so it seems to me that a slippy map layer that showed track logs would be a useful asset to the project.<br>

Hi,<br>
<br>
Is there any layer presenting ONLY raw GPS data?<br>
<br>
Actually, we have Mapnik, Osmarender, Maplint, but what about a layer<br>
with only raw GPS data. This could be usefull (at least for me) to<br>
manage my own traces. Could be usefull to easily decide if a zone need<br>
some GPS traces or not.<br>
<br>
What difficulties to host a new layer?<br>
Somewhere to host tiles?<br>
I'm quite sure that tiles@home model can be enough to compute such tiles.<br>
