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 <http://code.google.com/intl/en/apis/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" and "apikey" parameters are not supported.
The parameters "region", "language", and "bounds" 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>). The default is
"false".
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"
},
{

],
"short_name" => "Mitte",
"long_name" => "Mitte"
},
{
"types" => [

],
"short_name" => "Berlin",
"long_name" => "Berlin"
},
{

},

"political"
],
"short_name" => "DE",
"long_name" => "Germany"
},
{
"types" => [
"postal_code"
],
"short_name" => 10117,
"long_name" => 10117
}
],
"geometry" => {

"lng" => "13.3617711"
},

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.
