Expanded Description:
All survey marks or objects used by the UK Ordnance Survey, Ordnance Survey Northern Ireland (OSNI) Ordnance Survey Ireland (OSI)& EA Environment Agency. Can include Cut bench marks, Rivets, Flush Brackets, Trig pillars in fact any point used and recorded by ordnance survey, OSNI or OSI. This category can include Triangulation Stations placed by the Admiralty Hydrographic Department that feature on various points around the UK coast. Can also include EABM (Environment Agency Bench Mark). Trigpoints are the common name for "triangulation pillars". These are concrete pillars, about 4' tall, which were used by the Ordnance Survey in order to determine the exact shape of the country. They are generally located on the highest bit of ground in the area, so that there is a direct line of sight from one to the next. By sitting a theodolite (an accurate compass built into a telescope) on the top of the pillar, accurate bearings to nearby trigpoints could be taken.
This category also includes any confirmed other Ordnance Survey marks such as cut bench marks, O/S tide markers, OS rivets, OS bolts, Fundamental bench marks, surface blocks, Berntsen's, blocks, passive and active GPS active stations and flush bracket's on constructions other than trig pillars. Many cut bench marks can be researched on www.old-maps.co.uk (1890's OS maps) which show their exact location and height. If you know of any other easily accessible resources please let group know.

EABM's are placed by the Environment Agency

Here are definitions of common OS marks.
OSBM BOLT "OSBM Bolt" is quite large - an inch or two in diameter (25 - 50mm) (sizes vary), with letters "O S B M" and an arrow engraved into the Bolt itself.(Some of the older ones have no markings.) Bolt
1GL BOLT or PA BOLT1GL BOLT or PA BOLT is a cut mark with a small bolt. The bolt can be next to the cut benchmark or in the apex. 1GL BOLT or PA BOLT
CUT BENCHMARK A cut mark in stone/brick. Some have been found upside-down. CUT BENCHMARK
RIVET WITH CUT BENCHMARK. A rivet is a small round headed bolt no more than half and inch (12mm) in diameter. They are situated ABOVE a cut benchmark. RIVET WITH CUT BENCHMARK
FUNDAMENTAL BENCHMARK. These are about a foot high (30 cm) with a large bolt on top, with a metal plaque. Worth noting also is that some standard FBMs have been cut down to ground level. Some of these have a new bolt on top, but not all. FUNDAMENTAL BENCHMARK
FLUSH BRACKET. These can be found on trig pillars, buildings, bridges etc. They all have an individual number, which you should log. FLUSH BRACKET
SURFACE BLOCK. A rivet set in a concrete base about 6 inches across (15cm) flush at ground level. SURFACE BLOCK
RIVET AND BENCHMARK (OLD STYLE) I have been told that it is the old style of rivet. It is like a headless nail which has been driven into the granite. The top of the stump protrudes out of the rock by about a quarter of an inch (6mm). The only place I have found one is on Dartmoor, where there are several. RIVET AND BENCHMARK (OLD STYLE)
