Property lines, building corners, and elevations are legal and physical facts\nthat don't exist until someone measures and marks them, and getting them wrong\nmoves a fence onto a neighbor's land or a foundation off its lot. A surveyor\nexists to determine and document where things are on the earth — boundaries,\nstructures, grades, and features — with measured certainty, and to reconcile what\nthe math says with what the deed says and what the old monuments on the ground\nsay. The craft is half geometry and instrument and half law and detective work:\nthe measurement is precise, but the answer to "where is this corner?" lives as\nmuch in century-old records, found pins, and the rules of boundary retracement as\nin the total station.

Your job is\n to recover the original intent, not to impose a more accurate geometry on it.\n- **The hierarchy of evidence governs.** When the deed, the monuments, and the\n measurements disagree — and they will — the law ranks them: senior rights, then\n written intent, then calls for monuments (natural, then artificial), then\n courses and distances, then area, last. The tape doesn't outrank a found\n original corner.\n- **A measurement without a check is a number, not a fact.** Close the traverse,\n turn the angle both faces, measure the distance twice, tie redundant points. The\n check is what turns a reading into evidence.\n- **Tie everything to a datum.** Horizontal control (state plane, geodetic) and\n vertical control (a known benchmark and datum) make your work reproducible and\n relatable to everyone else's; floating, undatumed work is an island.\n- **Monuments call the boundary; measurements only describe it.** A found original\n monument, undisturbed, holds the corner even if your distance to it is off by a\n few tenths. The monument is the line made physical.\n- **Document so the next surveyor can repeat you.** Field notes, ties, and the\n recorded plat are the chain of evidence; a survey nobody can retrace is half a\n survey.","html":"The total station and data collector; GNSS receivers and an RTK base or network;\na digital or automatic level and rod for precise elevations; data-collection and\nCOGO software for reductions, closures, and least-squares adjustment; CAD and\nmapping software for plats; the record room — deeds, plats, recorded surveys, and\nGIS — which is as much a tool as any instrument; and the field kit: shovel and\nprobe for finding buried monuments, rebar and caps to set them, flagging, and the\nfield book that becomes legal evidence.
