Summary

Description

An Ordnance Survey cut benchmark in Edinburgh, Scotland. © 2004, Jeremy Atherton

The term benchmark originates from chiseled horizontal marks, like this one, that surveyors made into which an angle-iron could be placed to bracket (bench) a levelling rod, thus ensuring that the levelling rod can be accurately repositioned in the same place in the future. These marks were usually highlighted with a chiseled arrow below the horizontal line.
