I'd be interested in this. I know sources of data for both UK
Trigpoints and Benchmarks, the only problem could be the data
The OS also has a complete database of all trigpoints/benchmarks here:
The Trigonomy Yahoo group is the primary place for discussion of UK
trigpoints, they also have several complete excel databases that they
have transcribed from documents at the OS.
