Description

Gdaladdo fails in creating external overviews for some images. For example for a three channel image of size 72000 by 128000 pixels gdaladdo with -ro option starts building overview in normal tiff format. Before ovr file is ready it reaches 4 GB file size limit and operation fails. Having an option to force gdaladdo to create ovr file as BigTIFF would be beneficial.
