Detailed Description

Wrapper for GDALDataset representing a collection of associated Raster bands.

Constructor & Destructor Documentation

isce3::io::gdal::Dataset::Dataset	(	const std::string &	path,
		GDALAccess	access = `GA_ReadOnly`
	)

Open an existing file as a GDAL dataset.

Parameters

[in]	path	File path
[in]	access	Access mode

isce3::io::gdal::Dataset::Dataset	(	const isce3::io::IDataSet &	dataset,
		GDALAccess	access = `GA_ReadOnly`
	)

Create a dataset from an HDF5 dataset.

The resulting dataset is invalidated if the HDF5 file is closed.

Parameters

[in]	dataset	HDF5 dataset
[in]	access	Access mode

isce3::io::gdal::Dataset::Dataset	(	const std::string &	path,
		int	width,
		int	length,
		int	bands,
		GDALDataType	datatype,
		const std::string &	driver = `defaultDriver()`
	)

Create a new GDAL dataset.

Parameters

[in]	path	File path
[in]	width	Number of columns
[in]	length	Number of rows
[in]	bands	Number of bands
[in]	datatype	Data type identifier
[in]	driver	GDAL driver name

isce3::io::gdal::Dataset::Dataset	(	const std::string &	path,
		const Dataset &	src
	)

Create a new GDAL dataset as a copy of an existing dataset.

The duplicate is created with the same driver format as the original.

Parameters

[in]	path	File path of new dataset
[in]	src	Source dataset

isce3::io::gdal::Dataset::Dataset	(	const std::string &	path,
		const Dataset &	src,
		const std::string &	driver
	)

Create a new GDAL dataset as a copy of an existing dataset.

Parameters

[in]	path	File path of new dataset
[in]	src	Source dataset
[in]	driver	GDAL driver name

template<typename T >

isce3::io::gdal::Dataset::Dataset	(	const T *	data,
		int	width,
		int	length,
		int	bands
	)

inline

Create a read-only dataset describing an existing in-memory array.

The data layout is assumed to be in row major, band sequential format.

Parameters

[in]	data	Pointer to first pixel of first band
[in]	width	Number of columns
[in]	length	Number of rows
[in]	bands	Number of bands

template<typename T >

isce3::io::gdal::Dataset::Dataset	(	T *	data,
		int	width,
		int	length,
		int	bands,
		GDALAccess	access = `GA_Update`
	)

inline

Create a dataset describing an existing in-memory array.

The data layout is assumed to be in row major, band sequential format.

Parameters

[in]	data	Pointer to first pixel of first band
[in]	width	Number of columns
[in]	length	Number of rows
[in]	bands	Number of bands
[in]	access	Access mode

template<typename T >

isce3::io::gdal::Dataset::Dataset	(	const T *	data,
		int	width,
		int	length,
		int	bands,
		std::size_t	colstride,
		std::size_t	rowstride,
		std::size_t	bandstride
	)

inline

Create a read-only dataset describing an existing in-memory array.

Parameters

[in]	length	Number of rows
[in]	bands	Number of bands
[in]	colstride	Stride in bytes between the start of adjacent columns
[in]	rowstride	Stride in bytes between the start of adjacent rows
[in]	bandstride	Stride in bytes between the start of adjacent bands

template<typename T >

isce3::io::gdal::Dataset::Dataset	(	T *	data,
		int	width,
		int	length,
		int	bands,
		std::size_t	colstride,
		std::size_t	rowstride,
		std::size_t	bandstride,
		GDALAccess	access = `GA_Update`
	)

inline

Create a dataset describing an existing in-memory array.

Parameters

Member Function Documentation

GeoTransform isce3::io::gdal::Dataset::getGeoTransform ( ) const

Get transform from raster coordinates (pixel, line) to projected coordinates (x, y)

If no transform is found, the default (identity) transform is returned.

isce3::core::ProjectionBase * isce3::io::gdal::Dataset::getProjection ( ) const

Get spatial reference system.

Exceptions

isce3::except::GDALError if the spatial reference system is unavailable

Raster isce3::io::gdal::Dataset::getRaster ( int band ) const

Fetch raster band.

Parameters

[in] band Raster band index (1-based)

void isce3::io::gdal::Dataset::setGeoTransform ( const GeoTransform & transform )

Set geotransform.

Exceptions

isce3::except::GDALError if the format does not support this operation

void isce3::io::gdal::Dataset::setProjection ( const isce3::core::ProjectionBase * proj )

Set spatial reference system.

Exceptions

isce3::except::GDALError if the format does not support this operation
