NAME

Geo::Coder::Googlev3 - Google Maps v3 Geocoding API

SYNOPSIS

use Geo::Coder::Googlev3;

my $geocoder = Geo::Coder::Googlev3->new;
my $location  = $geocoder->geocode(location => 'Brandenburger Tor, Berlin');
my @locations = $geocoder->geocode(location => 'Berliner Straße, Berlin, Germany');

DESCRIPTION

Use this module just like Geo::Coder::Google. Note that no apikey is used in Google's v3 API, and the returned data structure differs.

Please check also https://developers.google.com/maps/documentation/geocoding/ for more information about Google's Geocoding API and especially usage limits.

CONSTRUCTOR

new

$geocoder = Geo::Coder::Googlev3->new;
$geocoder = Geo::Coder::Googlev3->new(language => 'de', gl => 'es');

Creates a new geocoding object.

The ua parameter may be supplied to override the default LWP::UserAgent object. The default LWP::UserAgent object sets the timeout to 15 seconds and enables the env_proxy option.

The Geo::Coder::Google's oe parameter is not supported.

The parameters region, language, bounds, and key are also accepted. The bounds parameter should be in the form:

[{lat => ..., lng => ...}, {lat => ..., lng => ...}]

The parameter sensor should be set to the string true if the geocoding request comes from a device with a location sensor (see https://developers.google.com/maps/documentation/geocoding/#GeocodingRequests). There's no default.

By default queries are done using http. By setting the use_https parameter to a true value https is used.

METHODS

geocode

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

Queries $location to Google Maps geocoding API. In scalar context it returns a hash reference of the first (best matching?) location. In list context it returns a list of such hash references.

The returned data structure looks like this:

{
  "formatted_address" => "Brandenburger Tor, Pariser Platz 7, 10117 Berlin, Germany",
  "types" => [
    "point_of_interest",
    "establishment"
  ],
  "address_components" => [
    {
      "types" => [
        "point_of_interest",
        "establishment"
      ],
      "short_name" => "Brandenburger Tor",
      "long_name" => "Brandenburger Tor"
    },
    {
      "types" => [
        "street_number"
      ],
      "short_name" => 7,
      "long_name" => 7
    },
    {
      "types" => [
        "route"
      ],
      "short_name" => "Pariser Platz",
      "long_name" => "Pariser Platz"
    },
    {
      "types" => [

        "political"
      ],
      "short_name" => "Mitte",
      "long_name" => "Mitte"
    },
    {
      "types" => [
        "locality",
        "political"
      ],
      "short_name" => "Berlin",
      "long_name" => "Berlin"
    },
    {
      "types" => [
        "administrative_area_level_2",
        "political"
      ],
      "short_name" => "Berlin",
      "long_name" => "Berlin"
    },
    {
      "types" => [
        "administrative_area_level_1",
        "political"
      ],
      "short_name" => "Berlin",
      "long_name" => "Berlin"
    },
    {
      "types" => [
        "country",
        "political"
      ],
      "short_name" => "DE",
      "long_name" => "Germany"
    },
    {
      "types" => [
        "postal_code"
      ],
      "short_name" => 10117,
      "long_name" => 10117
    }
  ],
  "geometry" => {
    "viewport" => {
      "southwest" => {
        "lat" => "52.5094785",
        "lng" => "13.3617711"
      },
      "northeast" => {
        "lat" => "52.5230586",
        "lng" => "13.3937859"
      }
    },
    "location" => {
      "lat" => "52.5162691",
      "lng" => "13.3777785"
    },
    "location_type" => "APPROXIMATE"
  }
};

The raw option may be set to a true value to get the uninterpreted, raw result from the API. Just the JSON data will be translated into a perl hash.

$raw_result = $geocoder->geocode(location => $location, raw => 1);

region

Accessor for the region parameter. The value should be a country code ("es", "dk", "us", etc). Use this to tell the webservice to prefer matches from that region. See the Google documentation for more information.

language

Accessor for the language parameter.

bounds

Accessor for the bounds parameter.

sensor

Accessor for the sensor parameter.
