NAME Geo::Coder::Google - Google Maps Geocoding API SYNOPSIS use Geo::Coder::Google; my $geocoder = Geo::Coder::Google->new(apikey => 'Your API Key'); my $location = $geocoder->geocode( location => 'Hollywood and Highland, Los Angeles, CA' ); DESCRIPTION Geo::Coder::Google provides a geocoding functionality using Google Maps API. METHODS new $geocoder = Geo::Coder::Google->new(apikey => 'Your API Key'); $geocoder = Geo::Coder::Google->new(apikey => 'Your API Key', host => 'maps.google.co.jp'); Creates a new geocoding object. You should pass a valid Google Maps API Key as "apikey" parameter. When you'd like to query Japanese address, you might want to set *host* parameter, which should point to *maps.google.co.jp*. I think this also applies to other countries like UK (maps.google.co.uk), but so far I only tested with *.com* and *.co.jp*. geocode $location = $geocoder->geocode(location => $location); @location = $geocoder->geocode(location => $location); Queries *$location* to Google Maps geocoding API and returns hash refernece returned back from API server. When you cann the method in an array context, it returns all the candidates got back, while it returns the 1st one in a scalar context. When you'd like to pass non-ascii string as a location, you should pass it as either UTF-8 bytes or Unicode flagged string. Returned data structure is as follows: { 'AddressDetails' => { 'Country' => { 'AdministrativeArea' => { 'SubAdministrativeArea' => { 'SubAdministrativeAreaName' => 'San Francisco', 'Locality' => { 'PostalCode' => { 'PostalCodeNumber' => '94107' }, 'LocalityName' => 'San Francisco', 'Thoroughfare' => { 'ThoroughfareName' => '548 4th St' } } }, 'AdministrativeAreaName' => 'CA' }, 'CountryNameCode' => 'US' } }, 'address' => '548 4th St, San Francisco, CA 94107, USA', 'Point' => { 'coordinates' => [ '-122.397323', '37.778993', 0 ] } } AUTHOR Tatsuhiko Miyagawa <[email protected]> This library is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
