WebThe GDALSuggestedWarpOutput () function is used to determine the bounds and resolution of the output virtual file which should be large enough to include all the input image If you want to create an alpha band if the source dataset has none, set psOptionsIn->nDstAlphaBand = GDALGetRasterCount (hSrcDS) + 1. WebGDAL provides a number of operations that can be employed to create new files from bands. For instance, the gdal.Polygonize (...) function can be used to create a vector dataset from a raster band by forming polygons from adjacent cells that have the same value. To apply the function, we first create a new vector dataset and layer in it.
