WWW::MapBlast - latitude & longitude from postal codes.

SYNOPSIS

        use WWW::MapBlast;
        my ($lat, $lon) = WWW::MapBlast::latlon('United Kingdom','BN3 3AG');
        __END__;

DESCRIPTION

Simply accesses MapBlast.com and retrieves latitude and longitude information.

Only minimal error checking, so have a look through the source before you use.

Commentary

Set $CHAT if you wish to see what's going on during net access.

Subroutine latlon (country, postcode)

Accepts a country name and a postal code, returns the relative latitude and longitude as defined by MapBlast.com

The argument country must match a key of the module's %countriesList hash, so it may be an idea to check your input against those keys before calling.

Will try to connect four times, and return undef on failure.

Note that latitude and longitude is not (x,y) !

LATITUDE AND LONGITUDE

After http://www.mapblast.com/myblast/helpFaq.mb#2:

Zero degrees longitude goes through Greenwich, England. Again, Each 69 miles from this meridian represents approximately 1 degree of longitude. East/West is plus/minus respectively.
