OpenStreetMap

Never ending edits

Posted by kucai on 10 August 2020 in English (English).

I believe I cleared most of east coasts’ osmose warnings a while ago. However, new warnings/errors keep popping up. Either osmose revised their rules, or new (non-local) mappers keep adding stuff that trigger osmose’s detection algorithm.

Also these mappers keep re-aligning existing ways to Maxar, despite there’s no indication that the new imagery is any more accurate than Bing. When 90% of the area was traced to Bing, why shift a portion to Maxar? If that’s the intention, why not shift everything to Maxar while you are at it and make them standardized. It’ll surely do wonders to your KPI, in addition to your ‘smoothing’ of highways.

That and reclassifying highways in a country you never step foot on.

Kratom mixed with Coke sounds good now…

Have you tried communicating with these mappers? If you don’t talk to them, they’ll have no idea what kind of work you’re doing on the map and they’ll keep doing what they perceive as a “fix”. If you have a local community, suggest the mappers to get in touch with it.

Remember to be polite. You could even suggest alternatives that would benefit your community (maybe tracing buildings from imagery could help better, or retracing the whole coast to Maxar, or something else that can be done remotely). If after that, they still continue to change the map in a way your community doesn’t like, contact the DWG, they’ll help you.

I did, here and there… But there are hoardes of em! :)

We’ll probably figure out something later on how to proceed with these issues. In the mean time, I’ll leave DWG out for the more serious googly type issues.

Thanks for you input.

This is SPARTAA!! hehe

Yeah, if they’re too many, you can’t handle them all yourself… Maybe there’s a reason why they come and map Malaysia? Have you tried asking them why they map in your country? Maybe there’s a root cause for these changes, like a forum post or an organization, then you could fix that and all these mappers will suddenly do the right thing (well… hopefully ^^)

If they are tourists, you could suggest that they use streetcomplete, or add details from the ground instead.

By the way, I use https://resultmaps.neis-one.org/osm-change-tiles to help me keep track of edits in my local area. It might be easier to use it to detect new mappers in your region and react more quickly than having to wait for osmose :)

I admire that you even attempt to fix all the Osmose errors in your area. . .

I am still trying to simply fix the ones that list me as last editor: Fix a TIGER road that crosses a bunch of imported waterways and you have a bunch of Osmose errors under your name. And then there are waterways that simply disappear into the desert, I know of no way to indicate to the QA tools that this is not a mistake.

There was this discussion in the tagging ML recently: https://lists.openstreetmap.org/pipermail/tagging/2020-July/054073.html. They didn’t come to a conclusion concerning waterways that disappear in the desert though.

@n76: I had this happen when I did some mapping in the UK, Puerto Rico, and a couple of other places. Finally I got sick of seeing the Osmose errors under my name so I went back and fixed them where I could. Even though Osmose has a disclaimer saying “not all of these may be this user’s fault” that’s still the implication more or less.
