GetDriver

 my $driver = $dataset->GetDriver;

GetWidth

 my $w = $dataset->GetWidth;

GetHeight

 my $h = $dataset->GetHeight;

GetSize

 my @size = $dataset->GetSize;

Returns the size (width, height) of the bands of this raster dataset.

GetBand

 my $band = $dataset->GetBand($i);

Get the ith (by default the first) band of a raster dataset.

GetBands

 my @bands = $dataset->GetBands;

Returns a list of Band objects representing the bands of this raster dataset.

CreateLayer

 my $layer = $dataset->CreateLayer({Name => 'layer', ...});

Create a new vector layer into this vector dataset.

Named arguments are the following.

"Name"

Optional, string, default is ''.

"GeometryType"

Optional, default is 'Unknown', the type of the first geometry field; note: if type is 'None', the layer schema does not initially contain any geometry fields.

"SpatialReference"

Optional, a SpatialReference object, the spatial reference for the first geometry field.

"Options"

Optional, driver specific options in an anonymous hash.

"Fields"

Optional, a reference to an array of Field objects or schemas, the fields to create into the layer.

"GeometryFields"

Optional, a reference to an array of GeometryField objects or schemas, the geometry fields to create into the layer; note that if this argument is defined then the arguments GeometryType and SpatialReference are ignored.

GetLayerCount my $count = $dataset->GetLayerCount();

GetLayer

 my $layer = $dataset->GetLayer($name);

If $name is strictly an integer, then returns the (name-1)th layer in the dataset, otherwise returns the layer whose name is $name. Without arguments returns the first layer.

CopyLayer

 my $copy = $dataset->CopyLayer($layer, $name, {DST_SRSWKT => 'WKT of a SRS', ...});

Copies the given layer into this dataset using the name $name and returns the new layer. The options hash is mostly driver specific.

ExecuteSQL $dataset->ExecuteSQL ($sql, $filter, $dialect);

 #  build a spatial index
 $dataset->ExecuteSQL (qq{CREATE SPATIAL INDEX ON "$some_layer_name"});
 
 #  filter a data set using the SQLite dialect and a second geometry
 my $filtered = $dataset->ExecuteSQL (
   qq{SELECT "$fld1", "$fld2" FROM "$some_layer_name"},
   $some_geometry,
   'SQLite',
 );

Info

 my $info = $dataset->Info($options);

Translate

 my $target = $source->Translate($path, $options, $progress, $progress_data);
