Hello everybody,
I am trying to build overviews in a VRT dataset with python GDAL.
I try this code:
out_vrt = os.path.join(out_dir, 'mosaic.vrt')
ds = gdal.BuildVRT(out_vrt, [raster1.tif, raster2.tif])
factors = [128, 256, 512]
gdal.SetConfigOption('COMPRESS_OVERVIEW', 'DEFLATE')
ds.BuildOverviews("AVERAGE", factors)
, but I get this error:
ERROR 6:
/home/umberto/Documents/jrc/FB_Data4Good/mosaic/test/vrt/mosaic.vrt:
BuildOverviews() not supported for this dataset.
The VRT mosaic is created, but the overviews are not.
As far as I know, gdaladdo should work with VRTs, but I am not sure if
gdal.BuildVRT() is actually using it.
Any idea?
