Module 2: Titles, Technical Descriptions, and Record Research - Worked Examples
These examples turn title and survey records into a checked pre-field geometry while preserving traceability to the original sources.
Extracting the Parcel Record Header
A title copy lists Lot 18, Psd-00-012345, a stated area of 600 m², and a technical description tied to an identified reference point. Prepare the minimum record header for the survey file.

A training parcel runs 30.000 m east, 20.000 m south, 30.000 m west, and 20.000 m north from its starting point. Check coordinate closure.

0 of 3 Steps CompletedDiagnosing a Nonclosing Rectangle from a Short Course
Starting at m, m, a training description calls for 30.000 m east, 20.000 m south, 30.000 m west, then 19.800 m north. Check whether the recorded courses close.

0 of 3 Steps CompletedSuspected Transposed Distance in a Technical Description
A title copy lists one course as 24.50 m, while an approved plan copy appears to show 42.50 m. The 24.50 m value produces a large misclosure.
Step-by-Step Solution
0 of 3 Steps CompletedFour-Course Record Reconstruction and Area Reconciliation
A training parcel begins at m, m. The source technical description lists the four courses below, while the client packet reports an area of m². Reconstruct the geometry, check closure and area, and decide what can be released.
| Course | Record bearing | Distance |
|---|---|---|
| 1 | 50.000 m | |
| 2 | 44.721 m | |
| 3 | 53.852 m | |
| 4 | 31.623 m |
This is an idealized practice dataset with rounded bearings and distances. Treat the computed area as a diagnostic until the misclosure and source-record basis are reviewed; the example supplies no acceptance tolerance and authorizes no correction.
