turf.dart

pub package

THIS PROJECT IS WORK IN PROCESS

A turf.js-like geospatial analysis library working with GeoJSON, written in pure Dart.

This includes a fully RFC 7946-compliant object-representation and serialization for GeoJSON.

Most of the implementation is a direct translation from turf.js.

Tests and Benchmarks

Tests are run with dart test and benchmarks can be run with dart run benchmark

Any new benchmarks must be named *_benchmark.dart and reside in the ./benchmark folder.
