A small library that convert one part of geographical coordinates from degree minutes format to decimal format and vice versa. More conversions to follow.

Toolkit for mapping elements of sets into geometric objects.

Finds the angle formed by two adjacent segments.

Plain color conversion functions

Lightweight utility for input validation and data extraction in Turf.js. Ensures GeoJSON inputs are in the correct format and extracts specific components like coordinates or geometries.

Measures the straight-line distance between two points, like cities or landmarks.

Converts a source-map from/to different formats and allows adding/changing properties.

Takes two points and finds the geographic bearing between them.

Takes two points and calculates a point midway between them geodesically.

Calculate great circles routes as LineString or MultiLineString.

Calculates the distance along a rhumb line between two points.

Returns the shortest path from start to end without colliding with any Feature in obstacles.

Takes a Point and calculates the ellipse polygon given two semi-axes expressed in variable units and steps for precision.

Takes two points and finds the bearing angle between them along a Rhumb line.

Loose geographic coordinate parsing library (designed for user input)

File-backed MCP server for coordinating multiple AI coding agents (Claude Code, Cursor, Cline, etc.). Local stdio or networked over Streamable HTTP.

Useful for extracting only the part of a route between waypoints.

Convert tabs to spaces in a string

Tiny millisecond conversion utility

Convert the result of `process.hrtime.bigint()` to seconds, milliseconds, nanoseconds
