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
