NAME

Geo::Coder::Google::V3 - Google Maps Geocoding API V3

SYNOPSIS

  use Geo::Coder::Google;

  my $geocoder = Geo::Coder::Google->new(apiver => 3);
  my $location = $geocoder->geocode( location => 'Hollywood and Highland, Los Angeles, CA' );

DESCRIPTION

Geo::Coder::Google::V3 provides a geocoding functionality using Google Maps API V3.

METHODS

new

  $geocoder = Geo::Coder::Google->new(apiver => 3);
  $geocoder = Geo::Coder::Google->new(apiver => 3, language => 'ru');
  $geocoder = Geo::Coder::Google->new(apiver => 3, gl => 'ca');
  $geocoder = Geo::Coder::Google->new(apiver => 3, oe => 'latin1');

To specify the language of Google's response add language parameter with a two-letter value. Note that adding that parameter does not guarantee that every request returns translated data.

You can also set gl parameter to set country code (e.g. ca for Canada).

You can ask for a character encoding other than utf-8 by setting the oe parameter, but this is not recommended.

You can optionally use your Maps Premier Client ID, by passing your client code as the client parameter and your private key as the key parameter. The URL signing for Premier Client IDs requires the Digest::HMAC_SHA1 and MIME::Base64 modules. To test your client, set the environment variables GMAP_CLIENT and GMAP_KEY before running 02_v3_live.t

  GMAP_CLIENT=your_id GMAP_KEY='your_key' make test

geocode

  $location = $geocoder->geocode(location => $location);
  @location = $geocoder->geocode(location => $location);

Queries $location to Google Maps geocoding API and returns hash reference 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.

reverse_geocode

  $location = $geocoder->reverse_geocode(latlng => '37.778907,-122.39732');
  @location = $geocoder->reverse_geocode(latlng => '37.778907,-122.39732');

Similar to geocode except it expects a latitude/longitude parameter.

ua

Accessor method to get and set UserAgent object used internally. You can call env_proxy for example, to get the proxy information from environment variables:

  $coder->ua->env_proxy;

You can also set your own User-Agent object:

  $coder->ua( LWPx::ParanoidAgent->new );
