What is Angle, COGO Resection, Traverse & Highway Curve Studio?

Angle, DMS, Gon, Radian & Surveyor Bearing Studio converts plane angles simultaneously across Decimal Degrees, Sexagesimal DMS (° ′ ″), Centesimal Gradians (gon), Radians (with symbolic π fractions), Milliradians, NATO Mils, Arcminutes/Arcseconds, Turns, and Surveyor Quadrant Bearings, alongside a horizontal circular curve solver.

How to use Angle, COGO Resection, Traverse & Highway Curve Studio in 3 steps
  1. 1

    Enter any angle in Degrees, DMS, Gon, Radians, or Mils

    Supports negative angles, >360° multi-turn values, and flexible DMS notation.

  2. 2

    Set 0–16 decimal precision & inspect normalized bearings

    View [0°, 360°) azimuth, [-180°, 180°) principal angle, back azimuth, and N/S E/W quadrant bearing.

  3. 3

    Solve circular curve geometry

    Switch to the Curve & Arc tab to compute arc length, chord, tangent, sagitta, and external distance.

Key features and benefits
  • Handles sexagesimal carry-over rounding cleanly (59.9999″ rolls into minutes/degrees without outputting 60″).
  • Combines angular unit conversion with surveyor quadrant bearings and highway curve geometry.
Common use cases

Converting French/Moroccan centesimal theodolite readings (gon) to DMS and radians.

Checking road alignment curve arc length, long chord, and tangent distance from radius R and deflection Δ.

Why browser-based works better

Angle, COGO Resection, Traverse & Highway Curve Studio consolidates related gis, surveying & cad studios workflows into one cohesive, multi-mode browser studio — eliminating tab-hopping across fragmented single-purpose tools.

Every mode executes locally using Web APIs and audited client-side libraries, so private files, tokens, and source code never leave your device.

Angle, COGO Resection, Traverse & Highway Curve Studio FAQs

Quick answers about the workflow, privacy, and where this tool fits in a broader job.

How are negative angles normalized for bearings?

Raw unit conversions preserve the negative sign, while the Azimuth Protractor normalizes modulo 360° into [0°, 360°) clockwise from North.
