Geo-Hashing version 0.01 ======================== NAME Geo::Hashing - Perl library to calculate Geohashing points SYNOPSIS use Geo::Hashing; my $g = new Geo::Hashing(lat => 37, lon => -122, date => "2008-05-24"); printf "Today's location is at %.6f, %.6f.\n", $g->lat, $g->lon; DESCRIPTION This module allows calculating the locaiton of Geohashes as described in http://wiki.xkcd.com/geohashing/Main_Page. METHODS new Create a new Geo::Hashing object. lat Set or get the points latitude. When settings, only the integer portion is considered. Set to undef to just get the offset. lon Set or get the points longitude. When settings, only the integer portion is considered.

If not set, it will be automatically retrieved depending on the value of $self->source. source Set the source of the DJIA opening data. Will load Geo::Hashing::Source::Name and call get_djia($date). See Geo::Hashing::Source::Random for a sample. use_30w_rule Set or get the 30w flag. Will be set automatically if lon is set and is greater than -30. debug Enable or disable diagnostic logging INSTALLATION To install this module type the following: perl Makefile.PL make make test make install DEPENDENCIES This module requires these other modules and libraries: Digest::MD5 LWP::Simple (if using the default Geo::Hashing::Source::Peeron) SEE ALSO Original comic: http://www.xkcd.com/426/ Wiki: http://wiki.xkcd.com/geohashing/Main_Page IRC: irc://irc.xkcd.com/geohashing COPYRIGHT AND LICENCE Put the correct copyright and licence information here.
