NAME

Geo::PostalCode::InstallDB - Create and install a new location database for Geo::PostalCode.

SYNOPSIS

  use Geo::PostalCode::InstallDB;

  Geo::PostalCode::InstallDB->install(zipdata => 'Geo-PostalCode_19991101.txt',
                                      db_dir  => '.')
    or die "Couldn't install DB!\n";

DESCRIPTION

This class contains only one useful method: install. It takes a text file, the name of which should be given in the zipdata parameter, and converts it into three Berkeley database files (postalcode.db, latlon.db, and city.db) which will be installed in the directory given as the db_dir parameter.

The format of these files is a series of lines, the first of which is skipped. Each has five tab-seperated values:

  postal_code   lat     lon     city    state
