3/ First letโ€™s look at some examples. Some countries take disputes very seriously, and legally you can only show the border they deem to be correct.

A famous โ€œactiveโ€ case is the border between India ๐Ÿ‡ฎ๐Ÿ‡ณ and Pakistan ๐Ÿ‡ต๐Ÿ‡ฐ

4/ Occasionally disputes lead to violence and escalate into all out war, as sadly seen recently between Armenia ๐Ÿ‡ฆ๐Ÿ‡ฒ and Azerbaijan ๐Ÿ‡ฆ๐Ÿ‡ฟ

5/ Happily not all border disputes lead to violence. Often the disputes are small and the parties just โ€œagree to disagreeโ€.

One such example we covered in our #geoweirdness thread about non-state territories of the United States: both the US ๐Ÿ‡บ๐Ÿ‡ธ and Haiti ๐Ÿ‡ญ๐Ÿ‡น claim tiny Navassa Island

6/ There are some very creative border dispute solutions - for example the tiny mid-river island that changes country between Spain ๐Ÿ‡ช๐Ÿ‡ธ and France ๐Ÿ‡ซ๐Ÿ‡ท every 6 months.

7/ And sometimes disputes are resolved peacefully, as was the case recently between Canada ๐Ÿ‡จ๐Ÿ‡ฆ and Denmark ๐Ÿ‡ฉ๐Ÿ‡ฐ ๐Ÿ‡ฌ๐Ÿ‡ฑ who settled their disagreement over the ownership of tiny Hans Island - site of the delightful "Whiskey War" which involved trading bottles of alcohol ๐Ÿพ to show possession of the island

8/ Many border disputes are caused by rivers changing their course.

Look at the border between the US ๐Ÿ‡บ๐Ÿ‡ธ states of Mississippi and Arkansas. The border follows the path of the river as it once was, not as it now is.

9/ In many places there are disagreements about which side of the river/water the border is on.

For example between Germany ๐Ÿ‡ฉ๐Ÿ‡ช and the Netherlands ๐Ÿ‡ณ๐Ÿ‡ฑ at the mouth of the Ems river

10/ Sometimes disputes arise because the old methods of surveying the border werenโ€™t very accurate. This can lead to surprises when the border is re-surveyed using more modern technologies, like this example between US ๐Ÿ‡บ๐Ÿ‡ธ states North and South Carolina.

11/ There are even bizarre situations where two bordering countries claim to both NOT own territory.

See for example the case of "Liberland" on the Danube which is claimed by neither Croatia ๐Ÿ‡ญ๐Ÿ‡ท nor Serbia ๐Ÿ‡ท๐Ÿ‡ธ

We covered it in our #geoweirdness thread about Croatia:

12/ So with all this disagreement, how does our geocoding API handle disputes? Who is โ€œrightโ€?

We use the main OpenStreetMap database which follows the principal of "most widely internationally recognised and best meets realities on the ground". Here's the OpenStreetMap Foundation's official policy doc: wiki.osmfoundation.org/wiki/Fi

13/ The great thing about #OpenStreetMap: OSM is a database, not a map. If you disagree with the OSMF's view you are free to take a copy, and use it to make maps showing the world the way you think it should be - whatever your view.

Several local OSM communities do this.

14/ Borders are a passionate topic, there aren't always simple answers.

Want more disputed borders? As always, wikipedia is the place for comprehensive list:

15/ The list of disputes is long and complicated - this thread could go on and on, but we'll wrap up this week's #geoweirdness thread there.

Thanks for reading and boosting.

We have more threads about specific countries, geocoding, etc on our blog.
