Dear all,
Ordnance Survey has a database of triangulation stations and their
precise locations as OSGB36 (National Grid) co-ordinates publicly
available here:

Thanks David. I have contacted OS using the contact form on their
website in the hope that they may publish the data under the OGL. I
think it would be helpful in accurately determining imagery offset.
Thanks,
Greg.

It is a pity that the gps passive stations are not included. Example:

Could you clarify if by merge/import you mean it to be performed
manually or programmatically?
Personally I think manually is the way to go, possibly as a Quarterly
Project asimilar to the schools update. Local knowledge will definitely
produce more accurate results.
I'd use P2's Task to save
Hi Dave F,
I haven’t thought too much about the process at this stage, but I was imagining
it would be done mostly programatically as there are 21,000+ (non-destroyed)
stations.
However, I was anticipating that there would have to be at least some manual
intervention to decide whether OS trig
