Turf¶
Turf.js is a spatial analysis library for JavaScript
applications. The turf module is a Kotlin port with support for Kotlin
Multiplatform and Java projects.
This module uses the classes from the geojson module as
GeoJSON inputs to turf functions.
Documentation for ported functions can be found in the API docs, while details on each function are available on the Turf.js site.
Installation¶
commonMain {
dependencies {

Example¶
Turf functions are available as top-level functions in Kotlin and as static methods in Java.
val point = Position(-75.0, 45.0)
val (longitude, latitude) = point.offset(100.kilometers, Bearing.North)
Position origin = new Position(-75.0, 45.0);
Position dest = offset(origin, 100, Kilometers, 0);
dest.getLongitude();
dest.getLatitude();
