The easiest approach is to traverse your list of locations and compute the distaance of each location from your designated position. To get locations of zip codes, try Geo::Coder::US:
use Geo::Coder::US; Geo::Coder::US->set_db( "geocoder.db" ); my ($ora) = Geo::Coder::US->geocode( "1005 Gravenstein Hwy N, 95472" ); print "O'Reilly is located at $ora->{lat} degrees north, " "$ora->{long} degrees east.\n";
To compute distances, use Geo::Ellipsoid:
use Geo::Ellipsoid; $geo = Geo::Ellipsoid->new(ellipsoid=>'NAD27', units=>'degrees'); @origin = ( 37.619002, -122.374843 ); # SFO @dest = ( 33.942536, -118.408074 ); # LAX ( $range, $bearing ) = $geo->to( @origin, @dest ); ($lat,$lon) = $geo->at( @origin, 45.0, 2000 ); ( $x, $y ) = $geo->displacement( @origin, $lat, $lon ); @pos = $geo->location( $lat, $lon, $x, $y );
