=head1 NAME

Geo::GDAL - Perl extension for the GDAL library for geospatial data

=head1 SYNOPSIS

  use Geo::GDAL;

  my $raster_file = shift @ARGV;

  my $raster_dataset = Geo::GDAL::Open($file);

  my $raster_data = $dataset->GetRasterBand(1)->ReadTile;

  my $vector_datasource = Geo::OGR::Open('./');
 
  my $vector_layer = $datasource->Layer('borders'); # e.g. a shapefile borders.shp in current directory

  $vector_layer->ResetReading();
  while (my $feature = $vector_layer->GetNextFeature()) {  
      my $geometry = $feature->GetGeometry(); 
      my $value = $feature->GetField($field);
  }

=head1 DESCRIPTION

This Perl module lets you to manage (read, analyse, write) geospatial
data stored in several formats.

=head2 EXPORT

None by default.
