Surveyor

Accurate measurement of the terrain is vital for major projects such as tunnel building. Using the triangulation method, surveyors were able to determine the route of the Gotthard railway tunnel with such precision that the two shafts met on 28 February 1880 with a horizontal discrepancy of just 33 cm. Electronic tools such as GPS and aerial and satellite photography source material have dramatically changed the surveyor’s job. This is reflected in the job title “geomatics technician” used today
