means The practice of precisely measuring land — its angles, distances, and elevations — to establish boundaries, maps, or construction layouts.

from From French 'surveier' — 'sur-' (over) plus 'veier' (to see), itself rooted in Latin 'videre,' to see. So surveying is literally 'overseeing' in the most physical sense: standing above the land and looking down to determine its true shape. The word kept its administrative flavor too — a 'surveyor' once just meant an overseer or inspector of anything, from customs houses to kitchens, before it narrowed, by the 1500s, into the specific craft of measuring ground with instruments and trigonometry.
