Survey Data Input & Validation

Choose the input that matches your data. Raw inputs are preserved and never overwritten by adjustments.

Or Paste Point Data (Pt, Northing, Easting, Elev, Desc)

Corner points must be listed in boundary order (clockwise or counter-clockwise). Coordinates are treated as PRS92 grid values of the active project's zone.

Observed Courses — one per line: Bearing, Distance (m)

Accepted bearing formats: N 45 30 20 E, N45-30-20E, S 10° 15' 30" W. For a closed traverse, list the courses in order around the boundary, returning to Point 1.

COGO & Traverse Adjustment (Compass / Bowditch Rule)

Linear misclosure and adjustment require observed courses (Bearing + Distance input mode). Coordinates imported directly form a mathematically closed figure.

Traverse Course Computations

Provide survey data in Stage 2 to compute traverse courses.

Lot Data Computation (LDC) Schedule

Tabulation of boundary bearings, distances, and coordinates.

Line	Bearing	Distance (m)	Northing (Y)	Easting (X)
No computation data available. Provide survey data first.

Interactive Map (Visualization Only)

PRS92 grid coordinates are transformed to WGS84 via proj4 for display. The basemap is for orientation only and is not a cadastral boundary authority.

Cursor: Move over map canvas

Datum: PRS92 / Zone 3 (EPSG:3123) → WGS84

Technical Description — Draft Generator

Metes-and-bounds draft compiled strictly from the computed courses. For review, correction, and approval by the responsible Geodetic Engineer.
