NAME

Geography::Countries::LatLong - mean latitude and longitude

SYNOPSIS

use Geography::Countries::LatLong;
if ( Geography::Countries::LatLong::supports('Hungary') ){
	my $array_ref    = latlong('Hungary');
	my ($lat, $long) = latlong_aspair('Hungary');
}

DESCRIPTION

This module provides mean latitude and longitude for a large number of countries named in English.

Regions and continents are not supported - please see the list below.

Look-up is by the English name of the country, as returned by the Geography::Countries module, of which this is a sub-class that exports none of its parent's properties or methods.

The mean values were arrived at with the following MATLAB code, where name is a country name recognised by MATLAB:

function [lat,lon] = country_latlon(name);
  load worldmtx;
  c=worldhi(name);
  lat = mean(c.latlim);
  lon = mean(c.longlim);
  fprintf( '"%s" => ["%.4f","%.4f"],', name,lat,lon);
% end function country_latlon

You will need the Mapping Toolbox to run the above snippet.
