    $w = new Geo::ReadGRIB "grib-file";
    $w->getFullCatalog;

    print $w->show,"\n";
  
    $plit = $w->extractLaLo(data_type, lat1, long1, lat2, long2, time);
    die $w->getError if $w->getError;

    # $plit is a Geo::ReadGRIB::PlaceIterator

    while ( $place = $plit->current() and $plit->next ) {

        # $place is a Geo::ReadGRIB::Place object

        $time       = $place->thisTime;
        $latitude   = $place->lat;
        $longitude  = $place->long;
        $data_types = $place->types; # an array ref of type names

        $data       = $place->data( data_type );

        # process data...
