My approach would be to use: - https://github.com/mapbox/togeojson <https://github.com/mapbox/togeojson> - to batch convert all the gpx -> geojson then - https://github.com/mapbox/tippecanoe <https://github.com/mapbox/tippecanoe> - to merge them all into a vector tileset. then - 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 > On Sep 14, 2018, at 9:56 AM, zhangy...@lewaimai.com wrote: > > yes，I only need to use the tracks to add roads to OSM once for each road at > the first time，but the problem is that how can I know whick roads are > missing，especial even the same road can have different GPS points in > different gpx files. <> > > it is a small city for china, the current data in OSM about the city is not > enough, many roads are missing，so I need to use the 100,000 gpx files to add > the missing roads，so i can get the bicycle distance between different points > of the city. > > of course, they are many repeated roads in <> the 100,000 gpx files, what I > need is the actual way info, how can I find them out? > > zhangy...@lewaimai.com <mailto:zhangy...@lewaimai.com> > > From: Simon Poole <mailto:si...@poole.ch> > Date: 2018-09-14 21:15 > To: dev <mailto:dev@openstreetmap.org> > Subject: Re: [OSM-dev] question about add way to openstreetmap by GPX > automatic > 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).
