COGO Survey Calculator

v2.3 makes the traverse honour From Point, finishes what v2.1 started, and fixes what an audit found: your azimuth-or-quadrant choice now applies everywhere, the standalone calculators start from your defaults, every tool explains itself, and the traverse editing workflow is airtight. • From Point now counts: a leg taken from an earlier station (say, two shots from point 4) is computed from that station. These sideshots are plotted and exported from their own station and stay out of the closure, area, and adjustment. Thanks to the surveyor who reported it. • Directions follow your Direction-entry setting — traverse leg rows, Line Tools, Common Tangent, and Two Unknowns show azimuth (or quadrant) first, with the other form beside it. • Bearing tools, the bearing ↔ azimuth converter, and the POB calculator start from your Preferences; POB gains azimuth entry and D M S. • Every calculator has a How to use button in its toolbar. • New Job opens the job straight away. • Angle-right legs remember their turned angle and backsight, so correcting an upstream leg re-turns the legs after it. • Fixed: deleting a middle leg now recomputes every later stored point; renaming a point follows through to the traverse; the edit sheet's Angle Right backsight defaults to the right station; a job unit change keeps unlabelled entered distances honest; the PDF report no longer prints a bearing for an exact closure; unparsable input can no longer produce NaN or infinite results. • Help & Guide: corrected descriptions for 3-Point Circle, Alignment, Area Partition, Recessed Invert, Closure & Area, and UTM, plus six new glossary terms.
