Apple App 'Go Map!!': Error when uploading the change sets

Question

Hello, just noticed that many of my edits in the app 'Go Map!!!' cannot be uploaded. The error message appears: "Cannot upload changes

Version mismatch: Provider 1, server had: 2 of Node 8784766722

POST https://api.openstreetmap.org/api/0.6/c ... 220/upload

The "raw XML data" can be edited in the 'Go Map!!!' app to "fix errors that prevent uploading." I don't know how though, Can delete and write there.

Maybe someone has a tip?

Thanks

The error seems to be a simple version conflict, to fix it you either need to not upload the element in question or, increase the version number to 2.

The former makes sense if your changes are incompatible (that is for example different, incompatible, tagging).

A simple text editor should be enough to do this, https://wiki.openstreetmap.org/wiki/OSM_XML gives some information on the XML format. Likely your edits are not in the normal XML format but in the https://wiki.openstreetmap.org/wiki/OsmChange format which just contains the changes.

Does Go Map!! have an "Update data" option like Vespucci or JOSM?

You can refresh GoMap!!'s OSM data under the "Display" menu (folded map icon on the right), under the "Clear Cache" submenu. Here you can select "Clear OSM Data" and then the map data will reload as needed when you browse the map. This will destroy any unsaved changes though. It's not possible to reload and preserve any unconflicting changes.

It seems you're attempting to use GoMap!!'s pre-upload changeset edit mode to resolve this conflict. That might work. As Simon says, you'd need to locate the XML element for the node in question, and either increase the version number (so you'll be overwriting the changes made in the previous version) or remove that entire node element from the changeset (so you'll be losing the changes you made to this node in GoMap!! and keeping the current OSM version.)

The problem is that editing the raw XML on a small touchscreen can be difficult, especially if you have over a hundred changes in that changeset. But if you're careful, you'll be able to scroll through and find the XML code for the correct node ID. Increasing the version number would probably be the easier approach, since it's a much smaller edit than deleting the whole node element. Normally I'd be wary about overwriting other mapper's changes but it looks like you're the one who actually made the change in the meantime, adding wheelchair=yes via StreetComplete, so overwriting probably wouldn't be a big problem. The wheelchair=yes tag would presumably survive, but if not you could fix it later.

GoMap!! can also email the changeset to you as an attachment. You could then examine it using a text editor on a desktop computer, which might help you find the spot that needs changed. You could even make the changes on the computer and email the changed file back to the phone, then try to copy and paste that changed version into GoMap!!'s edit screen.

You could also take the emailed changeset file and load it into JOSM, a desktop map editor. But JOSM has a steep learning curve so if you've never used it before that's a pretty daunting approach too. Another alternative might be Level0, a simplefied low-level OSM data editor where you could upload the modified changeset file and then commit it to the database. It's not particularly user-friendly either, though.

Good luck, J

Thank you for your detailed message.

I think it is clearly my fault. In app are 101 edits of nodes to upload. This can not do the app, the phone. I am using the app for the first time and thought it would work without the 'upload button'. It was late at night and I was under the impression.

I will delete many nodes now, after a copy of all the text.

But how do I delete correctly?? E.G.:

" <?xml version="1.0" encoding="UTF-8"?> <osmchange generator="Go Map!! 2.2.1" version="0.6"> <create> <node id="-5" timestamp="2021-06-05T22:24:08Z" version="1" lat="51.57168009376723" lon="8.105626210283127"> <tag k="tourism" v="information"></tag> <tag k="information" v="aus Kupfer, im Plaster, Mittelpunkt der Stadt Soest"></tag> <tag k="name" v="Koordinatenkreuz"></tag> <tag k="operator" v="Stadt Soest"></tag> </node> <node id="-4" timestamp="2021-06-05T22:04:09Z" version="1" lat="51.57272165414511" lon="8.106468646334125"> <tag k="tourism" v="information"></tag> <tag k="religion" v="Kontur im Pflaster sichtbar. In der Mitte befand sich ein hölzerner Pfahl."></tag> <tag k="information" v="Konturen im Pflaster erkennbar, in der Mitte stand ein Holzpfahl"></tag> <tag k="name" v="Pranger"></tag> <tag k="operator" v="Stadt Soest"></tag> </node> </create> <modify> <node id="4090388674" timestamp="2016-04-01T17:35:13Z" version="1" lat="51.5704817" lon="8.109112400000001">

  <tag k="phone" v="+49 2921 16380"></tag>
  <tag k="shop" v="tailor"></tag>
  <tag k="name" v="Jakob's Änderungsschneiderei"></tag>
  <tag k="stroller" v="yes"></tag>

Now, in this example, if I want to delete the node "4090388674", would I have to delete up to and including </node> , above it?

If I then want to delete the node "-4", would I then have to delete up to and including </node> , above it, again?

How many nodes can the app, the phone: iPhone 6 plus, probably upload at once?

Thanks for an answer.

I'm annoyed with myself for not uploading in between.

But this way I learn something.
