Note: GeoFeatures is currently being rewritten in pure Swift. This project will continue to be maintained until the production release of the Swift version.

Please see https://github.com/tonystone/geofeatures2 for the Swift rewrite.

GeoFeatures

Introduction

GeoFeatures is a lightweight, high performance geometry library for Objective-C. It supports the full set of geometric primitives such as Point, Polygon, and LineString as well as collection classes such as MultiPoint, MultiPolygon,and MultiLineString.

Features

• [x] Easy to use.
• [x] Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon, Box and GeometryCollection implementations.
• [x] Area, Length, BoundingBox, Centroid, Perimeter, Intersects, Intersection, Difference, Union, and Within (point in polygon) algorithms. More coming soon.
• [x] Immutable and mutable versions of all classes (e.g. GFPolygon and GFMutablePolygon).
• [x] WKT (Well-Known-Text) input and output.
• [x] GeoJSON input and output.
• [x] MapKit representations and drawing.
• [x] Indexed Subscripting support for all collection types (e.g. GEPoint * point = multiPoint[0]).
• [x] Swift: supports direct use in Swift applications.
• [x] CocoaPod framework support (compile as Objective-C framework or static lib).
• [x] Open Sourced under the the Apache License, Version 2.0.
• [x] Comprehensive doxygen documentation of the library available at github.io.
• [x] Implemented based on the popular and fast open source C++ boost geometry library.

Documentation

The doxygen documentation is online available at github.io.
