# NAME GIS::Distance::Fast - C implementation of GIS::Distance formulas. # DESCRIPTION This distribution re-implements some, but not all, of the formulas that come with [GIS::Distance](https://metacpan.org/pod/GIS::Distance) in the C programming language. C code is generally much faster than the Perl equivalent. See ["SPEED" in GIS::Distance](https://metacpan.org/pod/GIS::Distance#SPEED) for some benchmarking and how to run your own benchmarks. This module need not be used directly. [GIS::Distance](https://metacpan.org/pod/GIS::Distance) will automatically use the `GIS::Distance::Fast::*` formulas when installed. # FORMULAS - [GIS::Distance::Fast::Cosine](https://metacpan.org/pod/GIS::Distance::Fast::Cosine) - [GIS::Distance::Fast::GreatCircle](https://metacpan.org/pod/GIS::Distance::Fast::GreatCircle) - [GIS::Distance::Fast::Haversine](https://metacpan.org/pod/GIS::Distance::Fast::Haversine) - [GIS::Distance::Fast::Polar](https://metacpan.org/pod/GIS::Distance::Fast::Polar) - [GIS::Distance::Fast::Vincenty](https://metacpan.org/pod/GIS::Distance::Fast::Vincenty) # SUPPORT Please submit bugs and feature requests to the GIS-Distance-Fast GitHub issue tracker: [https://github.com/bluefeet/GIS-Distance-Fast/issues](https://github.com/bluefeet/GIS-Distance-Fast/issues) # AUTHORS ``` Aran Clary Deltac ``` # LICENSE This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
