=head1 NAME

Geo::Coder::All - Geo::Coder::All

=head1 VERSION

Version 0.05_01

=cut

our $VERSION = '0.05_01';


=head1 DESCRIPTION

Geo::Coder::All is wrapper for other geocoder cpan modules such as Geo::Coder::Google,Geo::Coder::Bing,Geo::Coder::Ovi,Geo::Coder::OSM and Geo::Coder::TomTom. Geo::Coder::All provides common geocode output format for all geocoder.


=head1 SYNOPSIS

    use Geo::Coder::All;
    #For google geocoder
    my $google_geocoder = Geo::Coder::All->new();#geocoder defaults to Geo::Coder::Google::V3
    #You can also use optional params for google api
    my $google_geocoder = Geo::Coder::All->new(key=>'GMAP_KEY',client=>'GMAP_CLIENT');

    #For Bing
    my $bing_geocoder = Geo::Coder::All->new(geocoder=>'Bing',key=>'BING_API_KEY');

    #For Ovi
    my $ovi_geocoder = Geo::Coder::All->new(geocoder=>'Ovi');

    #For OSM
    my $osm_geocoder = Geo::Coder::All->new(geocoder=>'OSM');

    #For TomTom
    my $tomtom_geocoder = Geo::Coder::All->new(geocoder=>'TomTom');

    #Currently supported geocoders are
    Geo::Coder::Google
    Geo::Coder::Bing
    Geo::Coder::TomTom
    Geo::Coder::Ovi
    Geo::Coder::OSM
    #only Geo::Coder::Google is installed by default if you need to use other then you should install them manually

    #IF you want use geocder that is not listed above then you can now specify fully qualified class wrapper name to add your own custom handling for response. Please have look at how Geo::Coder::All::Google is working.

=head1 METHODS

Geo::Coder::All offers geocode and reverse_geocode methods

=over 2

=item geocode

For Google geocoder , we can directly set the different geocoding options when calling geocode and reverse_geocode methods. i.e If you use Geo::Coder::Google you will have to create new instance every single time you need to change geocoding options

    $rh_location = $google_geocoder->geocode({location => 'London'});
    #above will return London from United Kingdom
    #With geocoding options
    #Following will return London from Canada as we used country_code is  ca (country_code is ISO 3166-1 )
    $rh_location = $google_geocoder->geocode({location => 'London',language=>'en',country_code=>'ca',encoding=>'utf8',sensor=>1});
    #in spanish
    $rh_location = $google_geocoder->geocode({location => 'London',language=>'es',country_code=>'ca',encoding=>'utf8',sensor=>1});
    #default encodings is set to 'utf8' you can change to other such as 'latin1'
    #You can also set DEGUB=>1 to dump raw response from the geocoder api

You cal also set GMAP_KEY and GMAP_CLIENT directly from geocode/reverse_geocode method and it will just work

=item reverse_geocode

For Google reverse_geocoder

    $rh_location = $google_geocoder->reverse_geocode({latlng=>'51.508515,-0.1254872',language=>'en',encoding=>'utf8',sensor=>1})
    #in spanish
    $rh_location = $google_geocoder->reverse_geocode({latlng=>'51.508515,-0.1254872',language=>'es',encoding=>'utf8',sensor=>1})
