Adding trails to OpenStreetMap (OSM) using GPS traces
Вставка

- This brief overview shows how to add trails to OpenStreetMap ( www.openstreet... ) using a GPX file you have recorded from a hike/bike ride. It uses the in-browser "iD" editor. For more details see learnosm.org/ and in particular the learnosm.org/en... guide.
How do you actually trace routes and get the gpx file, can I do it with a phone or do I need an tool or something
What I do, is go out for a hike and record a GPS track using any one of a number of apps on my phone to record the track. My personal favorite is Osmand, but there are many other options. You then export that track and get it onto your computer via some file transfer mechanism. Once it's on your computer, you can drag it onto JOSM or iD.
@@AdamFrancooh yeah the app is what I’m looking for Thanks!
I love collecting GPS data and uploading. I’ll leave the editing tracing stuff to anyone else to do though 😂 now that the tracks are there it should be accurate specially since I live in hilly area.
Thanks for the video. I have a GPX file from trailforks that's quite accurate. I don't want to have to go in and trace it. I have it imported as the pink line in OSM and I want to just convert the whole thing to a line so I can edit the tags. Any idea how to do this??
Hi Andrew, while this may be possible in the JOSM editor, josm.openstreetmap.de/ , Converting tacks to lines automatically isn''t possible in the browser-based iD editor. There are several reason why I don't do this though:
1. A single GPS trace tends to have a lot of error -- especially in forested areas or places near steep hill-sides, my tracks jump around a lot when I know the trail to be straight. The average of many tracks tends to be much more accurate than a single one, part of why using Strava's data for trail tracing is so useful: wiki.openstreetmap.org/wiki/Strava
2. GPS traces tend to have too many points, many more than are needed to represent the shape of the trail. JOSM includes a tool to simplify lines which can be helpful for this: josm.openstreetmap.de/wiki/Help/Action/SimplifyWay
3. You still need to make connections to other roads/trails. Especially in areas of dense trail-networks, I find it easier to make the connections while tracing than to hunt for close-but-not-quite-connected nodes.
4. I rarely stay on a single trail and remember to start recording exactly at the start/stop. With the tracing workflow, I just turn on the GPS at the beginning of an outing and leave it running the whole time. My track will include a bit of a parking area at the trail-head, plus wandering about at an overlook and similar deviations from the trail I'm trying to map. For my purposes, I've just found tracing to be less effort than cleaning up all of my extra deviations.
how do you download the map you editing? I wanna download the map for my country but it is too big..
Are you trying to download it for editing? If so, try zooming in and editing only a small portion. If downloading for use offline in an application, the technique would vary based on application.
No, I find out that the maps you download are not up to date with OSM website. I downloaded the map from here garmin.openstreetmap.nl/ but is from 27/05/2018 thats why it wasn't showing my just added routes... By the way, do you know when do they update the download links ?
Is there a way to have the editor draw missing lines for you, based on gpx track?

Excellent, thank you!
