Cadastral terminology: Is a “plat” a map of a relatively small tract that is plotted from a land survey, typically showing lots, boundaries, and easements?

Difficulty: Easy

Correct Answer: Correct

Explanation:


Introduction / Context:
Plats are central documents in land development, subdivision, and property conveyance. They depict surveyed parcels, rights-of-way, and easements at a scale suitable for legal recording and construction planning.



Given Data / Assumptions:

  • A plat is derived from field survey data.
  • It covers a limited area (subdivision, parcel, or block).
  • It includes bearings, distances, curve data, monuments, and notes.


Concept / Approach:
Unlike small-scale topographic maps, plats are large-scale legal depictions. They must match recorded deeds and include certifications, titles, legend, and approvals. The intent is precise property delineation, not generalized cartography.



Step-by-Step Solution:

Collect boundary and control data in the field.Compute and draft the parcel geometry with bearings and distances.Show monuments, easements, rights-of-way, and notes.Finalize with signatures and recordation per local regulations.


Verification / Alternative check:
Review a recorded subdivision plat at a county office: it will show exact metes-and-bounds and surveyors’ certifications, confirming the definition.



Why Other Options Are Wrong:

Incorrect: Opposes standard land surveying definitions.Hydrographic / federal only: Plats apply broadly to private and public lands as required.


Common Pitfalls:
Using small-scale base maps for legal description; omitting curve data; mismatching deed calls and survey geometry.


Final Answer:
Correct
