The principal triangnlation of the United Kingdom was finished in 1851; and the triangulations of. France, Belgium, Prussia, and Russia were so far advanced in 1860 that, if connected, we should have a continuous triangulation from the Island of Valentia, on the south-west extremity of Ireland, in north latitude 51° 55' 20", and longitude 10° 20' 40", west of Greenwich, to Orsk, on the River Ural in Russia. It was therefore possible to measure the length of an arc of parallel in latitude 52° of… Expand

A Different Kind of Longitude: The Metrology of Location by Geodesy
Histories of longitude often start with descriptions of maritime disasters that have been ascribed to the problem of finding longitude at sea. One much-cited example is that of the unfortunateExpand
The ‘nec plus ultra’ of precision measurement: Geodesy and the forgotten purpose of the Metre Convention
TLDR
By new research into the standards-in-use of the community of geodesists, the original purpose of the Metre Convention of 1875 is rediscovered, and the role of the coherence of the web of measurement in the context of change and improvement in standards is emphasised. Expand

WINTERBOTHAM WAS RIGHT!
Abstract Winterbotham was fully justified in his assumption that the Ordnance Survey standard bar OI1 has not changed its length between 1864 and 1906. That being the case, accurate metricExpand
