Which cadastre relies on computations from the actual ground survey to determine bearings and distances?

• A. Graphical Cadastre
• B. Numerical Cadastre
• C. Cadastral Surveys
• D. Public Land Surveys

Answer: (B)

Turning field measurements into a precise, coordinate-based map of parcels is the hallmark of numerical cadastre. It relies on actual ground survey data and uses mathematical computations to derive the bearings and distances, producing exact coordinates for parcel boundaries and ensuring consistency across the cadastral fabric. This rigorous computation step—often with adjustments to reduce errors—distinguishes it from approaches that focus mainly on graphic representation on a plan. Graphical cadastre emphasizes drawing and depiction of boundaries, while numerical cadastre centers on the mathematical processing of the survey data. The other terms describe broader survey concepts rather than the specific computational approach used to determine bearings and distances from field data.
