While editing in Merkaartor I was prevented from uploading changes because of a conflict. When I examined the conflict it turned out to be an entire road. However, I couldn’t figure out how to resolve the conflict. No conflicting points were highlighted, just an entire way. The Merkaartor manual (http://www.merkaartor.org/~bvh/manual/) states: “Note : conflict resolution for roads is not yet implemented.”
So, what to do? I could neither save nor upload the changes I made without resolving the conflict, but Merkaartor gave me no way to do so.
I don’t think there are any ways of resolving conflicts yet in any editor. Unfortunately you may have to start your editing from scratch with fresh OSM data.
No, actually. I’m sorry if I’m wrong. Does JOSM have conflict resolution, then?
I don’t use JOSM very much (I do use it though) and I had a nasty conflict a few months back whilst adding the Cotswolds AONB. Eventually I gave up and added it in Potlatch, which was very time consuming.
Yes, JOSM supports conflict resolution. I believe it is in active development, so parts might not yet be fully debugged, and there may be scenarios where no conflict resolution can succeed. But I ran into a conflict issue recently where a route relation was edited in another state during my edit session. JOSM’s relation conflict handled this perfectly - a multistep process that I had to think about, but in the end it worked!
A few months ago, the first month or 2 after API 0.6 went live, the conflict detection was very broken at times, or simply not working at other times. A lot has happened since then, but they still find the occasional issue now and then.
If Merkaartor has no conflict resolution whatsoever, I have to ask: which is the toy and which is the tool to actually get things done?
Merkaartor does have conflict resolution, just not with entire roads; points only. I suppose the tool you use is largely a matter of personal preference. I just find Merkaator to be more intuitive for this rank beginner. I find it much easier to trace GPS tracks with Merkaator than with JOSM.
Another question on conflicts: The conflict which Merkaator highlighted but could not resolve was an entire road. I later looked at the history for the area I was editing and couldn’t see an edit by anyone but me. How could a conflict arise in a situation like that?
