phpgeo - A Simple Geo Library for PHP
=====================================

[](#phpgeo---a-simple-geo-library-for-php)

phpgeo provides abstractions to geographical coordinates (including support for different ellipsoids) and allows you to calculate geographical distances between coordinates with high precision.

Features
--------

[](#features)

**Info:** Please visit the **[documentation site](https://phpgeo.marcusjaschen.de/)** for complete and up-to-date documentation!

phpgeo provides the following features (follow the links for examples):

- abstractions of several geometry objects ([coordinate/point](https://phpgeo.marcusjaschen.de/#_coordinate), [line](https://phpgeo.marcusjaschen.de/#_line), [polyline/GPS track](https://phpgeo.marcusjaschen.de/#_polyline), [polygon](https://phpgeo.marcusjaschen.de/#_polygon)
- support for different [ellipsoids](https://phpgeo.marcusjaschen.de/#_ellipsoid), e. g. WGS-84
- [length/distance/perimeter calculations](https://phpgeo.marcusjaschen.de/#_distance_and_length)with different implementations (Haversine, Vincenty)
- [Geofence](https://phpgeo.marcusjaschen.de/#_geofence_2) calculation, i. e. answering the question "Is this point contained in that area/polygon?"
- [formatting and output](https://phpgeo.marcusjaschen.de/#_formatting_and_output) of geometry objects (GeoJSON, nice strings, e. g. `18° 54′ 41″ -155° 40′ 42″`)
- calculation of [bearing angle between two points](https://phpgeo.marcusjaschen.de/#_bearing_between_two_points)(spherical or with Vincenty's formula)
- calculation of a [destination point for a given starting point](https://phpgeo.marcusjaschen.de/#_distance_between_two_coordinates_vincentys_formula), bearing angle, and distance (spherical or with Vincenty's formula)
- calculation of the [perpendicular distance between a point and a line](https://phpgeo.marcusjaschen.de/#_perpendicular_distance)
- getting segments of a [polyline](https://phpgeo.marcusjaschen.de/#_segments)/[polygon](https://phpgeo.marcusjaschen.de/#_segments_2),
- [reversing direction](https://phpgeo.marcusjaschen.de/#_reverse_direction_2)of polyline/polygon
