Surveyor’s Abbreviations

Here are some of the abbreviations you’re likely to find on one of our plat drawings. Surveyors who are resurveying a tract will often “find” evidence of earlier surveys and will “set” new markers of their own, which is why F (found) and S (set) are common in many of the abbreviations below.

PK Nail: A concrete nail made by Parker Kaelon (stamped PK) that marks a survey point; see also Hub and Tack in Surveyors' Slang.
