Oklahoma Land Surveyor (OLS) Exam study guide
Oklahoma Land Surveyor (OLS) Exam · Work through your exam, one topic at a time.
The Oklahoma Professional Surveyor licensure pathway runs through the Oklahoma State Board of Licensure for Professional Engineers and Surveyors (OKPES), which regulates surveying in the public interest. The board frames its mission plainly: "In order to safeguard life, health and property, and to promote the public welfare, the practice of engineering and surveying are declared to be subject to regulation in the public interest." Surveying licensure in Oklahoma follows a defined sequence: Surveyor Intern certification, then the Initial Professional Surveyor License, with separate comity and re-licensure applications for those who already hold credentials or are returning to practice. The Oklahoma Land Surveyor (OLS) Exam study guide has 6 sections and about 1,749 words.
01Boundary Surveying and Land Descriptions
This domain tests retracement doctrine and deed construction rather than original design: how Oklahoma surveyors weigh evidence, interpret calls, and resolve gaps and overlaps between adjoiners. Oklahoma follows the common-law rule that original monuments control over courses, distances, and area.
330 words, about 2 min02Geodetic and Control Surveying
This domain tests whether you can move between the ellipsoid, the geoid, a map projection, and the ground without mixing datums or dropping a scale factor. Horizontal coordinates in Oklahoma are commonly referenced to NAD83 (2011) and will migrate to the modernized NATRF2022; vertical coordinates use NAVD88 orthometric heights.
297 words, about 1 min03Cadastral and Public Land Survey System (PLSS)
Oklahoma has a dual cadastral fabric: PLSS coverage across the former Oklahoma Territory and much of the west, and allotment and metes-and-bounds boundaries across much of the former Indian Territory in the east. The Indian Meridian initial point lies near Davis in Murray County; the Cimarron Meridian governs the panhandle, with its initial point at 36°30' N, 103° W on the New Mexico line.
302 words, about 2 min04Survey Measurement and Computations
This domain tests closing, adjusting, and reporting measurements so the numbers you deliver are defensible. Close the angular work first, distributing angular error under an accepted rule, then compute latitudes and departures and assess linear misclosure.
249 words, about 1 min05Mapping, Platting, and Subdivision
This domain tests whether a plat is a legally sufficient instrument and a geometrically sound map: closure, dedication, monumentation, and consistency with deeds and ordinances. A subdivision plat identifies the subdivision, dedicates streets and easements, shows lot lines, dimensions, bearings, curve data, and monument positions, and carries the surveyor's seal and signature.
268 words, about 1 min06Professional Practice, Ethics, and Oklahoma Law
This domain tests the statutory and ethical frame around practice: licensure, responsible charge, sealing, records, and conflicts. Oklahoma regulates land surveyors under the Professional Engineers and Land Surveyors Act, 59 O.S.
