Border disputes - inconsistency in data and redering. Who can help?

General talk
1

There is an ongoing border dispute between Guyana-Suriname and French Guinea-Suriname.

It would be great if someone had the time to add the national borders claimed by Suriname so that the disputed area is properly represented. For example see the rendering in Google Maps.

The official data can be downloaded from gonini.org: Go to boundaries, Base layers on the left side of the layer, select ‘AOI’ from the small popup and download the shape file in zip format, which can then be converted into a gpx file (e.g. with shp-to-gpx converter) that can easily be imported into OSM as ‘GPS Traces’.

Both disputed borders already exists. Though the way they are mapped is inconsistent.

Thank you for your quick reply and your profound observation.
I also looked at the map, but I didn’t recognize it. Obviously I have tomatoes on my eyes or simply cannot read the dataset as good as you.

For the Surinamese, the current rendering in OSM is not acceptable, which is understandable.

Do you have any experience of how to resolve the inconsistency in the map? I have never had to deal with such a case of “border disputes”.

This is not really something I have experience in, so I’m afraid I can’t help you any further there. I do believe there are a few people active on the forum that know more about how border disputes are handled.

Ok. Thanks again!
I hope that anybody with special knowledge of border disputes will see this discussion and help out to get the rendering correct. It is good to know, that the correct data of the claimed borders in already in the system.

I’ve not looked at the data, but from reading what you have said it sounds like here that there can be no “correct” answer here that would satisfy both sides of the border.

OSM generally shows the “where you’d have to show your passport” border (if that can be thought of as relevant here). It sounds like you want to show something else. I’d suggest that you create a map based on OSM data that doesn’t include a border at all, and superimpose on that your desired boundaries (which it sounds like can also be based on OSM data).

There are lots of previous discussions with other links in this forum - hopefully they will be helpful to you.

Thank you for your reply and the reference to earlier discussions in the forum.

Yes, it might be difficult to show the border in a way that satisfies both sides.
But in the case of Suriname, Google’s rendered map shows it neutrally, with a dashed line along the disputed territory. Google Maps

In OSM, the border is shown to the disadvantage of Suriname, with no indication of an ongoing dispute. It would be great if the disputed borderlines were shown more neutrally in OSM. Here I have to acknowledge that the result on Google is better, but I hope that there is / will be a solution in OSM that is in no way inferior.

According to Guyane française – Suriname : le tracé définitif de la frontière officiellement fixé sur 400 km — Géoconfluences, it seems that the current point of view in OSM is rather close to the future treaty. So probaly what @SomeoneElse says about where you need to show your passport.
Anyway, we have an interesting example of border dispute between France and Italy. They agree to the validity of each treaty, but the treaties disagree in the border. And they agree… to disagree!
See Relation: 10629103 | OpenStreetMap and related Wikipedia links.
So those parts are in OSM parts of France and Italy, and the Wikipedia link is neither in French nor in Italian.
Best is to get in touch with local mappers on each side to see what is acceptable for both sides.
