VERSION

version 0.006

SYNOPSIS

    my $shp_writer = Geo::Shapefile::Writer->new( 'summits', 'POINT',
        [ name => 'C', 100 ],
        [ elevation => 'N', 8, 0 ],
    );

    $shp_writer->add_shape( [86.925278, 27.988056], 'Everest', 8848 );
    $shp_writer->add_shape( [42.436944, 43.353056], { name => 'Elbrus', elevation => 5642 } );

    $shp_writer->finalize();

DESCRIPTION

Geo::Shapelib is cool, but not portable.

So here is an alternative, if you need just simple shp export.

METHODS

new

    my $shp_writer = Geo::Shapefile::Writer->new( $name, $type, @attr_descriptions );

Create object and 3 associated files.

Possible types: POINT, POLYLINE, POLYGON (more to be implemented).

Possible attribute description formats:

  * scalar - just field name

  * arrayref - [ $name, $type, $length, $decimals ]

  * hashref - { name => $name, type => 'N', length => 8,  decimals => 0 } - CAM::DBF-compatible 

Default C(64) will be used if field is not completely described

add_shape

    $shp_writer->add_shape( $shape, @attributes );

$shape depends on file type:

  * point: [$x,$y]

  * polyline or polygon: [ [[$x0,$y0], ...], \@part2, ... ] 

Attributes are array or arrayref: [$val1, $val2, ...] or hashref: { $name1 => $val1, ...}

finalize

    $shp_writer->finalize();

Update global fields, close files
