NAME

Geo::Coder::OSM - Geocode addresses with the OpenStreetMap Nominatim API

SYNOPSIS

    use Geo::Coder::OSM;

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

DESCRIPTION

The Geo::Coder::OSM module provides an interface to the OpenStreet Nominatim geocoding service.

METHODS

new

    $geocoder = Geo::Coder::OSM->new()
    $geocoder = Geo::Coder::OSM->new(
        ua      => $ua,
        sources => [ 'osm', 'mapquest' ],
        debug   => 1,
    )

Creates a new geocoding object.

Accepts an optional ua parameter for passing in a custom LWP::UserAgent object.

Accepts an optional sources parameter for specifying the data sources. Current valid values are osm and mapquest. The default value is osm. To cycle between different sources, specify an array reference for the sources value. To define additional sources, see "SOURCES" below.

geocode

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

In scalar context, this method returns the first location result; and in list context it returns all location results.

Each location result is a hashref; a typical example looks like:

    {
        address => {
            city         => "Los Angeles",
            country      => "United States of America",
            country_code => "us",
            hamlet       => "Hollywood",
            road         => "Hollywood Boulevard",
            station      => "Hollywood/Highland",
            suburb       => "Little Armenia",
        },
        boundingbox => [
            "34.101634979248",   "34.1018371582031",
            "-118.339317321777", "-118.33910369873",
        ],
        class => "railway",
        display_name =>
            "Hollywood/Highland, Hollywood Boulevard, Little Armenia, Hollywood, Los Angeles, United States of America",
        icon =>
            "http://nominatim.openstreetmap.org/images/mapicons/transport_train_station2.p.20.png",
        lat => "34.101736",
        licence =>
            "Data Copyright OpenStreetMap Contributors, Some Rights Reserved. CC-BY-SA 2.0.",
        lon      => "-118.33921",
        osm_id   => 472413621,
        osm_type => "node",
        place_id => 9071654,
        type     => "station",
    }

reverse_geocode

    $location = $geocoder->reverse_geocode(lat => $lat, lon => $lon)
    $location = $geocoder->reverse_geocode(latlng => "$lat,$lon")

Returns a location result for the given lat/lon pair.

response

    $response = $geocoder->response()

Returns an HTTP::Response object for the last submitted request. Can be used to determine the details of an error.

ua

    $ua = $geocoder->ua()
    $ua = $geocoder->ua($ua)

Accessor for the UserAgent object.

SOURCES

To define additional sources add them to the %SOURCES package variable like so:

    $Geo::Coder::OSM::SOURCES{local} = 'http://127.0.0.1/api_base_path';
    $Geo::Coder::OSM::SOURCES{internal} = 'http://internal.corp/api_base_path';
