Land surveyor — how we know
The page itself gives the judgements. This one gives what they rest on: which technologies bear on the work, how the estimate moved since language models reached the public, and the method behind both.
Which technologies matter here#
Four separate signals. They are deliberately not added together — a job exposed to two technologies is not twice as exposed.
How it got here#
The index is not a static number. This is where it would have sat at each capability checkpoint since ChatGPT — reconstructed, and labelled as such.
—— this stretch contains a verified event- - - no event in this stretch — reconstruction only0 = no task exposed, 100 = every task exposed
● 4 verified events for this occupation, plotted at the date it happened — the parts of the line near a marker are anchored to something checkable.
Starts at 14 because total stations, GPS and CAD were standard before this chart begins, while fieldwork, setting out and boundary decisions were done by surveyors. It climbs as drones and laser scanners take over part of the measuring, governments allow aerial methods for official surveys, and machines guided by 3D designs replace stakes on large earthworks. It stays below the middle because rules keep boundary decisions and certification with licensed surveyors, and drone surveys still need ground measurement to fill gaps.
A flat line is not a forecast of safety. It says which tasks automation has reached so far — the occupations that moved least here are the ones where the constraint is physical or regulatory, and both of those can change.
