Category Proposal: Trig Points Ireland

Recommended Posts

Things > Benchmarks


Similar to UK Trigpoints this would cover traditional Triangulation pillars and OS markers (not GPS stations) as used on the island of Ireland by both OSNI and OSI.


The waypoints would require logging verification involving a photo of the marker and a GPS.


A full list of primary and secondary Trigs are available online giving Irish Grid coords so a photo is definitely required.

I suspect that the British colonies may have similiar if not the same type of Trig points. For example Australia and New Zealand have trig points which the same or pretty much the same.


I suspect these are similiar to the UK trig points. Frequently established for surveying or aerial navigation purposes. Does that sound right?


I don't know what benchmarks are so can't comment on those.
