NAME ^

WWW::Gazetteer::Getty - Find location of world towns and cities

SYNOPSYS ^

  use WWW::Gazetteer;
  my $g = WWW::Gazetteer::Getty->new('getty');
  my @londons = $g->find('London', 'UK');
  my $london = $londons[0];
  print $london->{longitude}, ", ", $london->{latitude}, "\n";
  my $nice = $g->find("Nice", "France")->[0];
  print $nice->{city}, ", ", $nice->{elevation}, "\n";

DESCRIPTION ^

A gazetteer is a geographical dictionary (as at the back of an atlas). The WWW::Gazetteer::Getty module uses the information at http://www.getty.edu/research/conducting_research/vocabularies/tgn/ to return geographical location (longitude, latitude) for towns and cities in countries in the world.

This module is a subclass of WWW::Gazetteer, so you must use that to create a WWW::Gazetteer::Getty object. Once you have imported the module and created a gazetteer object, calling find($country => $town) will return a list of hashrefs with longitude and latitude information.

  my @londons = $g->find('London', 'UK');
  my $london = $londons[0];
  print $london->{longitude}, ", ", $london->{latitude}, "\n";
  # prints -0.1167, 51.5000

The hashref for London actually looks like this:

  $london = {
    longitude => "-0.167",
    latitude  => "51.500",
    city      => 'London',
    country   => 'United Kingdom',
  };

The city and country values are the same as the ones you used. The longitude and latitude are in degrees, ranging from -180 to 180 where (0, 0) is on the Prime Meridian and the equator.

METHODS ^

new()

This returns a new WWW::Gazetteer::Getty object. It currently has no arguments:

  use WWW::Gazetteer;
  my $g = WWW::Gazetteer->new('getty');

find()

The find method looks up geographical information and returns it to you. It takes in a country and a city, with the recommended syntax being a city name and ISO 3166 code.

Note that there may be more than one town or city with that name in the country. You will get a list of hashrefs for each town/city.

  my @londons = $g->find("London", "UK");
  my @londons = $g->find("London", "United Kingdom");
