[OSM-dev] question about add way to openstreetmap by GPX automatic

My approach would be to use:
- https://github.com/mapbox/togeojson <https://github.com/mapbox/togeojson> - to batch convert all the gpx -> geojson
- https://github.com/mapbox/tippecanoe <https://github.com/mapbox/tippecanoe> - to merge them all into a vector tileset.
- upload that to Mapbox for hosting so that people can trace from it in the OSM editors.

But this is just one approach and there might be other tools that do this.
(I work for Mapbox, so I’m mostly familiar with our tools)

Thanks, Bryan

> You probably don't want to use the tracks directly to add roads to OSM (you would only want to do this once in any case). Definitely they could be useful for detecting which roads are missing, and, if the available aerial imagery  isn't good enough for actually adding any missing roads.
