Land Surveying Fundamentals and Practice
This domain tests the mathematical, legal, and field-practice foundation of land surveying in Hawaii. Questions combine measurement and adjustment, boundary retracement, coordinate systems, area/volume computations, and the Hawaii statutory and land-tenure context administered under HRS Chapter 457 by the Board of Professional Engineers, Architects, Surveyors, and Landscape Architects. Expect to choose the controlling evidence, perform a proportionate measurement, and recognize Hawaiian boundary terminology.
Core rules and concepts
- Measurement control and error. Distinguish random from systematic error; express closure as a ratio; adjust traverses only after checking angular closure. State plane coordinates are not ground distances: apply grid scale and elevation factors before comparing to field measurements.
- Boundary retracement hierarchy. Original monuments control; then natural monuments, artificial monuments, courses and distances, and area. A found original monument is not moved to fit record distance. For a lost corner, use proportionate measurement between reliable controlling corners; for an obliterated corner, use indirect evidence.
- Hawaii land tenure. Traditional divisions include ahupuaʻa, ʻili, and moʻo. Land Commission Awards (LCA), Royal Patents, kuleana, and government or homestead lands appear in chains of title. Descriptions may call for natural monuments such as streams, shoreline, or ridges and may use Hawaiian terms; do not assume every call is a metes-and-bounds bearing.
- Coordinates and computations. The Hawaii State Plane Coordinate System (NAD83) is a mapping tool; grid bearings and distances must be converted to ground before staking. Area is the weakest boundary evidence.
Worked example
Record: A–B = 100.00 ft, B–C = 150.00 ft; the original monument at B is lost. Found A and C are reliable; measured A–C = 248.00 ft. Record total A–C = 250.00 ft. Single proportionate position: AB′ = (100.00/250.00) × 248.00 = 99.20 ft; BC′ = 148.80 ft. Reason: the lost corner is reestablished on the record line in proportion to the original distances, not at the record distance from A.
Traps that cost marks
- Holding record distance over a found original monument.
- Using grid distance as ground distance without scale or elevation correction.
- Confusing ahupuaʻa with kuleana or treating area as controlling.
- Failing to distinguish lost from obliterated corners.
- Ignoring that only a licensed land surveyor may practice land surveying in Hawaii.
