A nearby playground was recently extended, and I'd like to map it. What's the best way to do so, considering:

- I don't have any aerial imagery of the new section
- I don't feel comfortable taking photos in a playground
- I find it too hard to map from memory

Any suggestions? My main concerns are getting the footpaths and scale correct.

Thanks to everyone who replied with suggestions! I haven't really done much GPS tracking/mapping, so it didn't occur to me to try that, but it makes perfect sense. I'll give it a go.
I just tested GPS tracking around my house with @CoMaps and it worked great!

@GuardedBear when I added more brand new stuff in my parents neighborhood I eyeballed it based off some pictures I took and old aerials. I added fixme= tags explaining that the were new and roughly placed and two years later I fixed them when we got new aerials.

It’s also not too hard to get a pretty decent geometry by going old school and pacing things off (recording with pen and paper!) You could find a measuring wheel which is also fun.

I am excited to hear what orher folks have used.

@GuardedBear a techie way: start a GPX trace, pace the perimeter 5 times, use that as anchor + non techie part: as @watmildon says, pen and paper. We all eyeball stuff, even with imagery we're not 100% sure it correctly aligned.

@GuardedBear I sometimes adjust geometry with mobile Go Map app. Walk around the playground, move the nodes and orthogonalise if needed.

You can also record your GPS trace, upload it and edit later in iD editor. This is best for big features as GPS is not that accurate.

@GuardedBear pending imagery a node might be fine, but if you want more detail you could get a GPS recording app and walk the paths a few times on different days to try to get an "average" location for them.

Use Vespucci or Field Papers to try to sketch in the outline and key bits of kit, benches etc. relative to the paths while you're there to eyeball it. Although that can also look weird.

@GuardedBear Walk the paths with a GPS (or 'phone, if it can) recording. Take a sketchpad and pencil, and scribble some aide-memoire sketches too. Then go home and do the mapping entry.

@GuardedBear just generate a GPX (aka recorded GPS positions) for the foot paths (best walk along them multiple times in both directions) and then use them to determine the geometry and position of the paths.

Just like in the good old days 😃

@GuardedBear What's wrong with just using GPS tracks and poi markers? That's how it all started in #Openstreetmap after all.
If you don't have one #OSMTracker might be an Option. https://wiki.openstreetmap.org/wiki/DE:OSMTracker_(Android)

@GuardedBear Vous pouvez créer une trace GPX avec votre téléphone en vous déplaçons déjà tout autour de la zone agrandie, puis ensuite le reporter sur OpenStreetMap. Et faire de même en ajoutant les points de repères pour les éléments rajouter dans la zones. Par exemple avec OpenTracks.

What about drawing on-site with #EveryDoor in notes mode?
@GuardedBear Actually, the playground mapping is one of the topics covered in the old Every Door introductory video: https://youtu.be/oQao9KgC5f8?si=p5rDZVubtvDIjFwK&t=120 :) I have mapped a few around my house when my kids were younger.

@GuardedBear
if you're on the ground, you could use #Vespucci. Just enable track recording, walk the path, and then draw it accordin to that track. Vespucci does have somewhat steep learning curve, though.

Another alternative is to use #StreetComplete - just long press on the screen and choose to create new track recording, and it will leave a note with track recording and description, which you can then draw as a proper `highway=path` in your familiar desktop editor when you're back home.

@GuardedBear If you have an android phone, you could try https://osmand.net/
That can log .GPX files which you can import into an editor.
it's been a few years since I used it though.
