Hi I am trying to clean the overviews from a GeoTIFF, but gdaladdo does not allow me. Is that an expected behaviour? Maybe I am missing more options. (there is no opposite of "-ro")
$ gdaladdo --debug on -clean out/test.tif GDAL: GDALOpen(out/test.tif, this=0x133058e00) succeeds as GTiff. GTiff: ScanDirectories() GTiff: Opened 6978x5110 overview. GTiff: Opened 3489x2555 overview. GTiff: Opened 1744x1277 overview. GTiff: Opened 872x638 overview. GTiff: Opened 436x319 overview. GTiff: File open for read-only accessing, creating overviews externally. ERROR 6: test.tif: Cannot add external overviews when there are already internal overviews Cleaning overviews failed. GDAL: GDALClose(out/test.tif, this=0x133058e00) $ gdaladdo --version GDAL 3.11.0 "Eganville", released 2025/05/06 I am running it on a Mac. Cheers, Javier.
