| Jan 8, 2021 at 0:31 | comment | added | Snowy | Hi Kazuhito, the GDAL aggregate within gdalwarp did the trick, using the max option. I found that using -ts worked with defining the output pixel size. If you want to enter an answer I will mark it as correct? | |

Am I right in thinking that you want to assign 1 to the coarser cells if any one of finer cells within it is 1? If yes, it looks like an Aggregate operation with maximum option.
