Orthodromic distance

I have spotted a difference between this page and the miror article of the French WP. The version in English (with this newspaper as source) claims that the islets are located 250 km from Japan proper (data given since 21 May 2005) and 216 km from mainland Korea (distance given since 19 September 2005). The version in French (with this site as reference) states that the rocks are situated only 212 km from Japan's main island.

So I used the WP page about Great-circle distance (and the miror articles in French and German) to try to verify, and two sites (lacosmo.fr and koordinaten.de) gave the same results: Liancourt West Island (37°14′31″N 131°51′55″E / 37.24194°N 131.86528°E / 37.24194; 131.86528 (West Islet)) is about 216 km from mainland Korea (37°03′40″N 129°26′18″E / 37.06111°N 129.43833°E / 37.06111; 129.43833) while the East Island (37°14′27″N 131°52′10″E / 37.24083°N 131.86944°E / 37.24083; 131.86944 (East Islet)) is about 212 km from Japan proper (35°28′12″N 132°43′41″E / 35.47000°N 132.72806°E / 35.47000; 132.72806).

I think the French version is correct and, if nobody objects, I will change the distance to 212 km. Ec.Domnowall (talk) 15:00, 31 March 2011 (UTC)[reply]

The distance you measured using the "Free Map Tool" is your original research and should not be used for Wikipedia. Here is a reliable source from the Ministry of Foreign Affair of Japan. It says 215km from Korea and 211km from Japan. ―― Phoenix7777 (talk) 00:50, 1 April 2011 (UTC)[reply]
I corrected it per MOFA page. Oda Mari (talk) 06:38, 1 April 2011 (UTC)[reply]
Original research was the figure you accepted for six years. And mathematics don't lie (in particular if the result has only a 1 km difference with official figures). It would have been more fair to say that my contribution was describing the reality and correcting an obvious mistake but that it was lacking an undisputed source. Anyway, thanks for finding an adequate reference. Ec.Domnowall (talk) 13:01, 1 April 2011 (UTC)[reply]
The WP:Original research policy came to be further and further established as Wikipedia matured. In the early days it didn't exist. In 2005 I think it only meant to original scientific research. Now it's a core policy. WhisperToMe (talk) 07:47, 15 July 2011 (UTC)[reply]

Naming consistency

We need some consistency for place names used in Wikipaedia.

The Pinnacle Islands (also called Diaoyu Islands in Chinese and Senkaku Islands in Japanese) is called Senkaku Islands in Wikipaedia because the islands are controlled by Japan.

Why is it that Dokdo (which is controlled by Korea) is called Liancourt Rocks here instead of Dokdo? The article name should be changed to Dokdo Marcopolo112233 (talk) 08:04, 26 July 2011 (UTC)[reply]
