NAME Geo::Coder::Yahoo - Geocode addresses with the Yahoo! API SYNOPSIS Provides a thin Perl interface to the Yahoo! Geocoding API. use Geo::Coder::Yahoo; my $geocoder = Geo::Coder::Yahoo->new(appid => 'my_app' ); my $location = $geocoder->geocode( location => 'Hollywood and Highland, Los Angeles, CA' ); OFFICIAL API DOCUMENTATION Read more about the API at . Yahoo! says that this API is deprecated and suggest using the placefinder API instead. There's a module for that in Geo::Coder::Placefinder. See also Geo::Coder::Many. PROXY SETTINGS We use the standard proxy setting environment variables via LWP. See the LWP documentation for more information. METHODS new $geocoder = Geo::Coder::Yahoo->new(appid => $appid) $geocoder = Geo::Coder::Yahoo->new( appid => $appid, on_error => sub { ... }, ua => LWP::UserAgent->new, ) Instantiates a new object. appid specifies your Yahoo Application ID. You can register at . If you don't specify it here you must specify it when calling geocode. on_error specifies an error handler to be called if the HTTP response code does not indicate success. The subroutine is called with the geocode object as the first argument and the HTTP::Response object as the second. The return value from the subroutine is used as the return value from "geocode". ua specifies the user agent object to use. If not set then a new LWP::UserAgent will be instanciated. geocode( location => $location ) Parameters are the URI arguments documented on the Yahoo API page (location, street, city, state, zip). You usually just need one of them to get results. "geocode" returns a reference to an array of results (an arrayref). More than one result may be returned if the given address is ambiguous. Each result in the arrayref is a hashref with data like the following example: { 'country' => 'US', 'longitude' => '-118.3387', 'state' => 'CA', 'zip' => '90028', 'city' => 'LOS ANGELES', 'latitude' => '34.1016', 'warning' => 'The exact location could not be found, here is the closest match: Hollywood Blvd At N Highland Ave, Los Angeles, CA 90028', 'address' => 'HOLLYWOOD BLVD AT N HIGHLAND AVE', 'precision' => 'address' } precision The precision of the address used for geocoding, from specific street address all the way up to country, depending on the precision of the address that could be extracted. Possible values, from most specific to most general are: address street zip+4 zip+2 zip city state country warning If the exact address was not found, the closest available match will be noted here. latitude The latitude of the location. longitude The longitude of the location. address Street address of the result, if a specific location could be determined. city City in which the result is located. state State in which the result is located. zip Zip code, if known. country Country in which the result is located. ua $ua = $geocoder->ua; $geocoder->ua( $new_ua ); Sets the user agent object to be used, if one is passed. Returns the user agent object. AUTHOR Ask Bjørn Hansen, "" BUGS Please report any bugs or feature requests to "bug-geo-coder-yahoo at rt.cpan.org", or through the web interface at .
