[edit] Merger

I've been bold and merged Trigonometrical station into this article, since there was clearly no justification in having two articles on the same topic. It could perhaps do with a bit of a prune from somebody knowledgeable to remove surplus information. I did the merge this way round because this article was here first, but if "Trigonometrical station" is the more commonly used term worldwide then maybe it should be moved. --Blisco 17:53, 1 October 2006 (UTC)

I think that Triangulation Station would be the best place for this article, as this is a name that is commonly used both in North America [1] and the UK [2].

What the Ordnance Survey actually use on the key to all their maps is Triangulation Pillar - a quotation in a glossary is not necessarily a definitive statement on the correct nomenclature. Velela 20:29, 1 October 2006 (UTC)

Looking at the pictures of trig points in Australia and NZ though, I shouldn't think you could call those 'pillars'. --Blisco 21:18, 1 October 2006 (UTC)

I wasn't trying to make a definitive statement on nomenclature, I was just giving a couple of examples of usage. Triangulation pillars are only one type of triangulation station used in the Ordnance Survey's network; for example, they also use surface blocks [3], bolts [4], and rivets [5]. In the US triangliation stations are usually just marked with disks similar to this benchmark disk, but the triangulation network also included prominent buildings, points marked with bolts or rivets, and sometimes pillars. --JeremyA 22:08, 1 October 2006 (UTC)

For the record, I wasn't dissenting from the use of Triangulation station, just clarifying that relying on a glossary wasn't an appropriate justification. However, it seems a general enough term to cover most uses. Velela 10:05, 2 October 2006 (UTC)
