Hi, Can you reproduce even with these three commands:
gdal_create -outsize 1000 1000 test.tif gdaladdo test.tif gdaladdo -clean test.tif If you can I fear the only solution is to say goodbye to Mac and switch to Windows ;) -Jukka Rahkonen- ________________________________________ Lähettäjä: Javier Jimenez Shaw Lähetetty: Maanantai 12. toukokuuta 2025 14.28 Vastaanottaja: Rahkonen Jukka Kopio: gdal dev Aihe: Re: [gdal-dev] I cannot clean overviews from GeoTIFF Thanks Jukka. That was my first guess.However before sending the email I checked it.
