A month ago (April 10), I noticed that the Belize/Guatemala border was very wrong. Several towns that were unquestionably part of Belize were shown to be on the wrong side of the border and in Guatemala instead. I fixed the border to be accurate (using the actual physical features that define the border), and double-checked it against maps.google.com, www.bing.com/maps/, and a CIA map. This put the towns back in the right countries (at least in edit view). A month later, the border in the non-editing interface is still wrong in all but 3 of the 19 zoom levels. In addition, if you search for a town like Jalacte, it still reports that the town belongs to Guatemala. How can this problem be fixed? |

Nominatim says Jalacte belongs to Petén, which in turn belongs to Guatemala. KeepRight says "The boundary of Petén is not closed-loop". The Petén (214699)-relation has this problem in a number of places. So, my guess is that the Petén relation is leaking. Fix the relation, and the problem might be gone. (But there are more "not closed-loop"-errors in the region, so new problems may arise.) How do you make a boundary closed-loop? I can't seem to even find the Petan border in the editing interface. Would anyone be able to help with this. I'm afraid it may be a bit over my head :(

I find it easier to fix boundary problems using JOSM, as the relation editor in JOSM shows very clearly when a boundary forms a closed loop or not. I just fixed both the Petén and Izabal boundaries. They still used the river centerline and were not connected to the west boundary of Belize.

Thanks! Hopefully that will help :)

After searching for 10 minutes or so I finally found the OSM bugtracking site and filed a bug: https://trac.openstreetmap.org/ticket/4857 Why is that site so secret? 1
Trac is for reporting bugs in software. What you found is a problem with the data, so it shouldn't go into trac.

Well, there's also the problem that the boundary changes I made only show up at 3 of the 19 zoom levels. There seems to be some sort of caching issue there.

That is probably a caching "problem" at your local PC. Try clearing your browser cache. If I click on the Jalacte link in gnurk's answer and slowly zoom out, then I see the blue circle on the Belize side of the boundary in zoom level 18 till 10. Zooming further out it impossible to tell the difference.

It's definitely not my browser cache. I can completely reset Safari and empty the cache and I still get the same behavior, plus it is consistent for me across different browsers. Zoom levels 1 (maximum zoom) and 2 show the correct updated boundary. Zoom 3 and 4 show the old boundary (for the most part). Zoom 5 and 6 show the updated boundary. Everything else shows the old boundary (with the border cutting straight through Jalacte instead of being to the west of it).
