Hi I am computing the overviews of a GeoTIFF on my own (using the GPU, much faster), and I want to include them in the tif file (also in the ovr sidecar file). What is the best way to do it? Just creating a multipage TIFF (I guess with the option APPEND_SUBDATASET=YES)? Is there anything else needed (metadata, tiff tags, etc)?
So far I want to do it in RGBA 8 bit images. (In the future I want to do it also in float32 images with nodata value and any number of bands, but no hurry). I am using GDAL 3.3.1 Any help is welcome. Thanks. Javier. .___ ._ ..._ .. . ._. .___ .. __ . _. . __.. ... .... ._ .__ Entre dos pensamientos racionales hay infinitos pensamientos irracionales.
