Destroy an open GDALDataset.. This is the accepted method of closing a GDAL dataset and deallocating all resources associated with it. Equivalent of the C callable GDALClose().Except that GDALClose() first decrements the reference count, and then closes only if it has dropped to zero.. For Windows users, it is not recommended to use the delete operator on the dataset object …

GetRasterBand (1) except RuntimeError, e: # for example, ... It turns out the gdal_polygonize utility just wraps a call to GDALFPolygonize so writing your own hacky polygonize Python script is pretty easy. The raster we are going to polygonize: from osgeo import gdal, ogr import sys # this allows GDAL to throw Python Exceptions gdal.

As described in the Raster Data Model, a GDALDataset contains a list of raster bands, all pertaining to the same area, and having the same resolution. It also has metadata, a coordinate system, a georeferencing transform, size of raster and various other information.

Fetch the number of raster bands on this dataset. More... GDALRasterBand *, GetRasterBand (int). Fetch a band object for a dataset. More..

for (int i = 1; i <= nbands; i++) { bands.add(new GDALBand(dataset.GetRasterBand(i)));

GDALRasterBand *GetRasterBand(int) Fetch a band object for a dataset. See GetBands () for a C++ iterator version of this method. Equivalent of the C function GDALGetRasterBand (). Parameters nBandId – the index number of the band to fetch, from 1 to GetRasterCount (). Returns the nBandId th band object Bands GetBands()

This method returns a table such that table [i] = j where i is an index of the 'this' rasterband and j the corresponding index for the reference rasterband. This method is thought as internal to GDAL and is used for drivers like RPFTOC. The implementation only supports 1 …

~GDALRasterBand() override Destructor. Applications should never destroy GDALRasterBands directly, instead destroy the GDALDataset. int GetXSize() Fetch XSize of raster. This method is the same as the C function GDALGetRasterBandXSize (). Returns the width in pixels of this band. int GetYSize() Fetch YSize of raster.
