Structured learning paths

Coordinate geometry for plane surveying — azimuth and quadrant bearings, polar ↔ rectangular conversion, worked examples, and common errors.

Closed traverses — departures and latitudes, linear misclosure, relative precision, Bowditch compass-rule adjustment, and a full worked example.

Three-point angular resection — Tienstra barycentric method, danger circle, field practice, worked example, and verification.

Planimetric area and perimeter from ordered E/N vertices — the Shoelace formula, winding order, worked example, and common pitfalls.

Browser-native GSI, CSV, and DXF conversion — survey workflows, USDM v1, client-side privacy, and quality checks.
