Class Dataset

  • public class Dataset
extends MajorObject
    Class Dataset is an uninstanciable class providing various methods to access a set of associated raster bands, usually from one file.

    The Dataset class is a binding for the C++ GDALDataset class.

    A dataset encapsulating one or more raster bands. Details are further discussed in the GDAL Data Model.

    Dataset objects are returned by methods from other classes, such as gdal.Open() or Driver.Create() / Driver.CreateCopy()

    • Method Detail

      • delete

        public void delete()
        Frees the native resource associated to a Dataset object and close the file.

        This method will delete the underlying C++ object. After it has been called, all native resources will have been destroyed, so it will be illegal (and likely to cause JVM crashes) to use any method on this object or any derived objects, such as Band objects of this Dataset.

        The delete() method must be called when a dataset has been opened in update or creation mode, otherwise data might not be properly flushed to the disk. You cannot rely on the finalization to call delete().

        Overrides:
        delete in class MajorObject

        Set the projection reference string for this dataset.

        The string should be in OGC WKT or PROJ.4 format. An error may occur because of incorrectly specified projection strings, because the dataset is not writable, or because the dataset does not support the indicated projection. Many formats do not support writing projections.

        Parameters:
        projection - projection reference string.
        Returns:
        gdalconst.CE_Failure if an error occurs, otherwise gdalconst.CE_None.

      • GetGeoTransform

        public void GetGeoTransform​(double[] geoTransformArray)
        Fetch the affine transformation coefficients.

        Fetches the coefficients for transforming between pixel/line (P,L) raster space, and projection coordinates (Xp,Yp) space. 

           Xp = geoTransformArray[0] + P*geoTransformArray[1] + L*geoTransformArray[2];
   Yp = geoTransformArray[3] + P*geoTransformArray[4] + L*geoTransformArray[5];

        In a north up image, geoTransformArray[1] is the pixel width, and geoTransformArray[5] is the pixel height. The upper left corner of the upper left pixel is at position (geoTransformArray[0],geoTransformArray[3]).

        The default transform is (0,1,0,0,0,1) and should be returned even when an error occurs, such as for formats that don't support transformation to projection coordinates.

        NOTE: GetGeoTransform() isn't expressive enough to handle the variety of OGC Grid Coverages pixel/line to projection transformation schemes. Eventually this method will be depreciated in favour of a more general scheme.

        Parameters:
        geoTransformArray - an existing six double array into which the transformation will be placed.
        See Also:
        gdal.ApplyGeoTransform(double[] padfGeoTransform, double dfPixel, double dfLine, double[] pdfGeoX, double[] pdfGeoY), gdal.InvGeoTransform(double[] gt_in)

      • SetGeoTransform

        public int SetGeoTransform​(double[] geoTransformArray)
        Set the affine transformation coefficients.

        See #GetGeoTransform() for details on the meaning of the geoTransformArray coefficients.

        Parameters:
        geoTransformArray - a six double array containing the transformation coefficients to be written with the dataset.
        Returns:
        gdalconst.CE_None on success, or gdalconst.CE_Failure if this transform cannot be written.
        See Also:
        GetGeoTransform(double[] geoTransformArray)

                          int[] overviewlist,
                          ProgressCallback callback)
        Build raster overview(s).

        If the operation is unsupported for the indicated dataset, then gdalconst.CE_Failure is returned, and gdal.GetLastErrorNo() will return gdalconst.CPLE_NotSupported.

        For example, to build overview level 2, 4 and 8 on all bands the following call could be made: 

           ds.BuildOverviews( "NEAREST", new int[] { 2, 4, 8 }, null );
        Parameters:
        resampling - one of "NEAREST", "GAUSS", "AVERAGE", "AVERAGE_MAGPHASE" or "NONE" controlling the downsampling method applied.
        overviewlist - the list of overview decimation factors to build.

                   java.lang.String GCPProjection)
        Assign GCPs.

        This method assigns the passed set of GCPs to this dataset, as well as setting their coordinate system. Internally copies are made of the coordinate system and list of points, so the caller remains responsible for deallocating these arguments if appropriate.

        Most formats do not support setting of GCPs, even formats that can handle GCPs. These formats will return CE_Failure.

        Parameters:
        gcpArray - array of GCP objects being assigned
        GCPProjection - the new OGC WKT coordinate system to assign for the GCP output coordinates. This parameter should be "" if no output coordinate system is known.
        Returns:

        Any raster (or other GDAL) data written via GDAL calls, but buffered internally will be written to disk.

        Calling this method is generally not sufficient to ensure that the file is in a consistent state. You must call delete() for that

      • AddBand

        public int AddBand​(int datatype,
                   java.util.Vector options)
        Add a band to a dataset.

        This method will add a new band to the dataset if the underlying format supports this action. Except VRT and MEM drivers, most formats do not.

        Note that the new Band object is not returned. It may be fetched after successful completion of the method by calling ds.GetRasterBand(ds.GetRasterCount()) as the newest band will always be the last band.

        Parameters:
        datatype - the data type of the pixels in the new band.
        options - a vector of options strings, each being "NAME=VALUE". The supported options are format specific. null may be passed by default.
        Returns:
        gdalconst.CE_None on success or gdalconst.CE_Failure on failure.

      • CreateMaskBand

        public int CreateMaskBand​(int nFlags)
        Adds a mask band to the current band.

        The default implementation of the CreateMaskBand() method is implemented based on similar rules to the .ovr handling implemented using the GDALDefaultOverviews object. A TIFF file with the extension .msk will be created with the same basename as the original file, and it will have as many bands as the original image (or just one for GMF_PER_DATASET). The mask images will be deflate compressed tiled images with the same block size as the original image if possible.

        Returns:
        gdalconst.CE_None on success or gdalconst.CE_Failure on an error.
        Since:
        GDAL 1.5.0

      • GetFileList

        public java.util.Vector GetFileList()
        Fetch files forming dataset.

        Returns a list of files believed to be part of this dataset. If it returns an empty list of files it means there is believed to be no local file system files associated with the dataset (for instance a virtual dataset).

        The returned filenames will normally be relative or absolute paths depending on the path used to originally open the dataset.

        Returns:
        null or a vector of strings of file names.

                             int nBandSpace)
        Read a region of image data from multiple bands.

        This method allows reading a region of one or more Band's from this dataset into a buffer. It automatically takes care of data type translation if the data type (buf_type) of the buffer is different than that of the Band. The method also takes care of image decimation / replication if the buffer size (buf_xsize x buf_ysize) is different than the size of the region being accessed (xsize x ysize).

        The nPixelSpace, nLineSpace and nBandSpace parameters allow reading into or writing from various organization of buffers.

        For highest performance full resolution data access, read on "block boundaries" as returned by Band.GetBlockSize(int[], int[]), or use the Band.ReadBlock(int, int, java.nio.ByteBuffer) method.

        When requesting a multi-byte datatype (GDT_Int16, GDT_Int32, GDT_Float32, ...), you should generally set the byte order of the buffer to the native order of the machine with nioBuffer.order(ByteOrder.nativeOrder()) (the default is BIG_ENDIAN) if you use the getShort(), getInt(), getFloat(), ... methods of the ByteBuffer class.

        Parameters:
        xoff - The pixel offset to the top left corner of the region of the band to be accessed. This would be zero to start from the left side.
        yoff - The line offset to the top left corner of the region of the band to be accessed. This would be zero to start from the top.
        xsize - The width of the region of the band to be accessed in pixels.
        ysize - The height of the region of the band to be accessed in lines.
        buf_xsize - the width of the buffer image into which the desired region is to be read.
        buf_ysize - the height of the buffer image into which the desired region is to be read.
        buf_type - the type of the pixel values in the nioBuffer data buffer. One of gdalconstConstants.GDT_Byte, gdalconstConstants.GDT_Int16, ... The pixel values will automatically be translated to/from the Band data type as needed.
        nioBuffer - The buffer into which the data will be written. This buffer must contain at least buf_xsize * buf_ysize * nBandCount words of type buf_type. It is organized in left to right,top to bottom pixel order. Spacing is controlled by the nPixelSpace, and nLineSpace parameters.
        band_list - the list of band numbers being read/written. Note band numbers are 1 based. This may be null to select the first nBandCount bands.
        nPixelSpace - The byte offset from the start of one pixel value in the buffer to the start of the next pixel value within a scanline. If defaulted (0) the size of the datatype buf_type is used.
        nLineSpace - The byte offset from the start of one scanline in the buffer to the start of the next. If defaulted the size of the datatype buf_type * buf_xsize is used.
        nBandSpace - the byte offset from the start of one bands data to the start of the next. If defaulted (zero) the value will be nLineSpace * buf_ysize implying band sequential organization of the data buffer.
        Returns:
        gdalconst.CE_Failure if the access fails, otherwise gdalconst.CE_None.
