chrisveness/geodesy

The **geodesy** repository provides a lightweight, language‑agnostic JavaScript library that implements a wide range of geospatial calculations—including distances, bearings, coordinate conversions (e.g., between latitude/longitude, Cartesian, UTM, MGRS, OS grid references, and datum transformations), and routing formulas—using both simple spherical and more accurate ellipsoidal/Vincenty models. It is intended for developers building GIS‑enabled web or Node.js applications, navigation tools, or any project that requires reusable, well‑documented geodesy functions without heavy dependencies
