NAME Geo::Ellipsoid - longitude and latitude calculations using an ellipsoid model Methods are now guaranteed to return angle values in the range [0,2pi) or [-pi,pi). The output range may be selected with arguments to the new() constructor method or by calling the set_longitude_symmetric or set_bearing_symmetric methods. Perls older than 5.6 are not supported. This module is a port of existing Fortran subroutines to Perl. INSTALLATION To install this module, unpack the distribution file, and run the following commands: perl Makefile.PL make make test make install SUPPORT AND DOCUMENTATION After installing, you can find documentation for this module with the perldoc command. perldoc Geo::Ellipsoid You can also look for information at: GitHub http://rt.cpan.org/NoAuth/Bugs.html?Dist=Geo-Ellipsoid MetaCPAN https://metacpan.org/release/Geo-Ellipsoid CPAN Ratings http://cpanratings.perl.org/d/Geo-Ellipsoid CPAN Testers PASS Matrix http://pass.cpantesters.org/distro/A/Geo-Ellipsoid.html CPAN Testers Reports http://www.cpantesters.org/distro/A/Geo-Ellipsoid.html CPAN Testers Matrix http://matrix.cpantesters.org/?dist=Geo-Ellipsoid COPYRIGHT AND LICENCE Copyright (C) 2016-2021 Peter John Acklam (current maintaner) Copyright (C) 2005-2008 Jim Gibson (original author) This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
