Forgive my likely stupidity, but I was trying to use the reference to the
gdal.Dataset in this way:
def silly_reference_ds(rb):
return rb.ds.GetGeoTransform()
ds = gdal.Open('L:/orcawa/spatial/topography/dem30')
rb = ds.GetRasterBand(1)
rb.ds = ds
print silly_reference_ds(rb)
such that I could pass around Bands instead of Datasets (and band numbers) to
functions, but still have reference to things like the geotransform. Am I way
off base?
thanks, matt
