Geo::GDAL::FFI - A foreign function interface to GDAL

=head1 VERSION

Version 0.06

=head1 SYNOPSIS

This is an example of creating a vector dataset.

 use Geo::GDAL::FFI qw/GetDriver/;

 my $sr = Geo::GDAL::FFI::SpatialReference->new(EPSG => 3067);
 my $layer = GetDriver('ESRI Shapefile')
     ->Create('test.shp')
     ->CreateLayer({
         Name => 'test',
         SpatialReference => $sr,
         GeometryType => 'Point',
         Fields => [
         {
             Name => 'name',
             Type => 'String'
         }
         ]
     });
 my $f = Geo::GDAL::FFI::Feature->new($layer->GetDefn);
 $f->SetField(name => 'a');
 my $g = Geo::GDAL::FFI::Geometry->new('Point');
 $g->SetPoint(1, 2);
 $f->SetGeomField($g);
 $layer->CreateFeature($f);

This is an example of reading a vector dataset.

 use Geo::GDAL::FFI qw/Open/;

 my $layer = Open('test.shp')->GetLayer;
 $layer->ResetReading;
 while (my $feature = $layer->GetNextFeature) {
     my $value = $feature->GetField('name');
     my $geom = $feature->GetGeomField;
     say $value, ' ', $geom->AsText;
 }

This is an example of creating a raster dataset.

 use Geo::GDAL::FFI qw/GetDriver/;

 my $tiff = GetDriver('GTiff')->Create('test.tiff', 3, 2);
 my $ogc_wkt =
        'GEOGCS["WGS 84",DATUM["WGS_1984",SPHEROID["WGS84",6378137,298.257223563,'.
        'AUTHORITY["EPSG","7030"]],AUTHORITY["EPSG","6326"]],PRIMEM["Greenwich",0,'.
        'AUTHORITY["EPSG","8901"]],UNIT["degree",0.01745329251994328,'.
        'AUTHORITY["EPSG","9122"]],AUTHORITY["EPSG","4326"]]';
 $tiff->SetProjectionString($ogc_wkt);
 my $transform = [10,2,0,20,0,3];
 $tiff->SetGeoTransform($transform);
 my $data = [[0,1,2],[3,4,5]];
 $tiff->GetBand->Write($data);

This is an example of reading a raster dataset. Note that using L
and L can greatly reduce the time needed to process large
raster datasets.

 use Geo::GDAL::FFI qw/Open/;

 my $band = Open($ARGV[0])->GetBand;
 my ($w_band, $h_band) = $band->GetSize;
 my ($w_block, $h_block) = $band->GetBlockSize;
 my $nodata = $band->GetNoDataValue;
 my ($xoff, $yoff) = (0,0);
 my ($min, $max);

 while (1) {
     if ($xoff >= $w_band) {
         $xoff = 0;
         $yoff += $h_block;
         last if $yoff >= $h_band;
     }
     my $w_real = $w_band - $xoff;
     $w_real = $w_block if $w_real > $w_block;
     my $h_real = $h_band - $yoff;
     $h_real = $h_block if $h_real > $h_block;

     my $data = $band->Read($xoff, $yoff, $w_real, $h_real);

     for my $y (0..$#$data) {
         my $row = $data->[$y];
         for my $x (0..$#$row) {
             my $value = $row->[$x];
             next if defined $nodata && $value == $nodata;
             $min = $value if !defined $min || $value < $min;
             $max = $value if !defined $max || $value > $max;

     }

=head1 DESCRIPTION

This is a foreign function interface to the GDAL geospatial data
access library.

=head1 IMPORTABLE FUNCTIONS

The most important importable functions are GetDriver and Open, which
return a driver and a dataset objects respectively. GetDrivers returns
all available drivers as objects.

Other importable functions include error handling configuration
(SetErrorHandling and UnsetErrorHandling), functions that return lists
of strings that are used in methods (Capabilities, OpenFlags,
DataTypes, ResamplingMethods, FieldTypes, FieldSubtypes,
Justifications, ColorInterpretations, GeometryTypes, GeometryFormats,
GridAlgorithms), also functions GetVersionInfo, HaveGEOS,
SetConfigOption, GetConfigOption, FindFile, PushFinderLocation,
PopFinderLocation, and FinderClean can be imported.

:all imports all above functions.

=head2 GetVersionInfo

 my $info = GetVersionInfo($request);

Returns the version information from the underlying GDAL
library. $request is optional and by default 'VERSION_NUM'.

=head2 GetDriver

 my $driver = GetDriver($name);

Returns the specific driver object.

=head2 GetDrivers

Returns a list of all available driver objects.

=head2 Open

 my $dataset = Open($name, {Flags => [qw/READONLY/], ...});

Open a dataset. $name is the name of the dataset. Named arguments are
the following.

=over 4

=item C

Optional, default is a reference to an empty array. Note that some
drivers can open both raster and vector datasets.

=item C

Optional, default is all drivers. Use a reference to an array of
driver names to limit which drivers to test.

=item C

Optional, default is to probe the file system. You may use a reference
to an array of auxiliary file names.

=item C

Optional, a reference to an array of driver specific open
options. Consult the main GDAL documentation for open options.

=back

=head2 Capabilities

Returns the list of capabilities (strings) a GDAL major object
(Driver, Dataset, Band, or Layer in Geo::GDAL::FFI) can have.

=head2 OpenFlags

Returns the list of opening flags to be used in the Open method.

=head2 DataTypes

Returns the list of raster cell data types to be used in e.g. the
CreateDataset method of the Driver class.

=head2 FieldTypes

Returns the list of field types.

=head2 FieldSubtypes

Returns the list of field subtypes.

=head2 Justifications

Returns the list of field justifications.

=head2 ColorInterpretations

Returns the list of color interpretations.

=head2 GeometryTypes

Returns the list of geometry types.

=head2 SetErrorHandling

Set a Perl function to catch errors reported within GDAL with
CPLError. The errors are collected into @Geo::GDAL::FFI::errors and
confessed if a method fails. This is the default.

=head2 UnetErrorHandling

Unset the Perl function to catch GDAL errors. If no other error
handler is set, GDAL prints the errors into stderr.

=head1 METHODS

=head2 get_instance

 my $gdal = Geo::GDAL::FFI->get_instance;

Obtain the Geo::GDAL::FFI singleton object. The object is usually not needed.
