Geo::Parse::OSM::Singlepass(3) User Contributed Perl Documentation Geo::Parse::OSM::Singlepass(3)

Geo::Parse::OSM::Singlepass - Single pass OpenStreetMap file parser

version 0.42

Geo::Parse::OSM::Singlepass extends Geo::Parse::OSM class to resolve geometry on one pass. It faster than ::Multipass, but uses much more memory and fails on old-style multipolygons.

    use Geo::Parse::OSM::Singlepass;

    my $osm = Geo::Parse::OSM::Singlepass->new( 'planet.osm.gz' );
    $osm->seek_to_relations;
    $osm->parse( sub{ warn $_[0]->{id}  if  $_[0]->{user} eq 'Alice' } );

    my $osm = Geo::Parse::OSM::Singlepass->new( 'planet.osm' );

Creates parser instance and makes one pass to load node coords, way chains and multipolygon lists.

You can add extra custom callback function 'pass1' for every object

    my $osm = Geo::Parse::OSM::Singlepass->new( 'planet.osm', pass1 => sub{ ... } );

Same as in Geo::Parse::OSM, but callback object has additional fields for multipolygon objects:

* outer - list of outer rings (ring is a closed list of node ids) * inner - inner rings

Returns coordinates of node.

    my ($lat,$lon) = $osm->latlon( '1234578' );
