Is comprised of all classes of surveys of isolated parcels of land used for agricultural, residential, commercial, resettlement, or other purposes covering areas not more than 1,500 hectares.

• A. Public Land Surveys
• B. Cadastral Surveys
• C. Group Settlement/Townsite Subdivision Surveys
• D. Isolated Surveys

Answer: (D)

This item tests how surveys are categorized by scope and size. Isolated surveys cover individual parcels of land used for various purposes—agricultural, residential, commercial, resettlement, or other uses—and each survey involves land not larger than 1,500 hectares. This focus on single, smaller parcels sets isolated surveys apart from other survey types. Cadastral surveys, for example, deal with larger tracts and form part of the formal cadastre for titling; group settlement or townsite subdivision surveys create multiple lots within a planned townsite; and public land surveys pertain to lands of the public domain, not specifically isolated parcels. Because the description emphasizes isolated parcels and the area cap of 1,500 hectares, it correctly identifies isolated surveys.
