Talk:Struve Geodetic Arc

Triangulation
What exactly is a triangulation? I looked at Triangulation article but it talks about geometry, not geography. Can anyone please link to a relevant article or write an explanation? Thanks. --Amir E. Aharoni 14:25, 19 September 2006 (UTC)
 * The article Geodesy describes the process. An explanation for earthlings can be found here: Finnish national land survey. There is also a good map showing the complete arc.
 * That "explanation for earthlings" link is now dead. PeterHansen (talk) 14:49, 19 April 2015 (UTC)

Faulty link
Can anybody tell me why the second, erratic InterWikilink to the Russian article, doesn't show itself to be erased? Islander(Scandinavia) 14:43, 3 October 2006 (UTC)
 * It was a side effect by poorly made template, I've removed it from there. -- Serguei Trouchelle 15:51, 3 October 2006 (UTC)

Suomenlinna?
Can I ask why is Suomenlinna linked to this page? Not apparently listed on the page itself. -- Cimon Avaro; on a pogostick. 09:02, 8 July 2007 (UTC)

Coordinates
Providing a single coordinate is pretty meaningless here IMHO. More interesting would be specifying the meridian along which (more or less) the arc runs, or maybe specifying two meridians between which the arc runs!? bamse (talk) 10:05, 22 October 2011 (UTC)

The arc must run along a meridian because the whole point is to use a Great Circle which passes through both poles and also crosses the Equator at right angles. I think the actual points have to be projected back to this meridian, both in latitude and distance. Then the analysis should be applied to these projected points. It is not clear to me which meridian was actually used. The Norwegian pamphlet (cited) provides a modern map that shows it as 26° 43' East, but also shows Struve's own map where it appears to pass through Fuglenes (23° 39'). It doesn't matter too much but it would be nice to know which meridian Struve actually used. Budhen (talk) 16:20, 10 June 2014 (UTC)
