Which cadastral survey involves bearings and distances computed based on actual ground survey?

• A. Numerical Cadastre
• B. Graphical Cadastre
• C. Cadastre
• D. Control Surveys

Answer: (A)

The test here is about how parcel boundaries are defined in a cadastral survey. When bearings and distances are computed from actual ground survey, the boundaries are described numerically in a coordinate system, with the corner positions determined through field measurements and then stored as coordinates. This approach is the essence of numerical cadastre: it uses computed, numeric coordinates rather than just a plotted graphic on a map.

Graphical cadastre emphasizes the drawn plan based on field measurements, often focusing on the map representation rather than the numeric coordinates. Control surveys deal with establishing and maintaining a framework of reference points for surveys, not specifically delineating parcels. A cadastre, in general, is the system of records for land parcels, but the description of coordinates derived from ground measurements specifically identifies numerical cadastre.
