Hi there. I am again in the course of creating overviews using gdaladdo and can't help feeling this could be faster...
Gdalwarp is much faster when resampling an image. You can use -multi and tune memory usage. So why can't gdaladdo? Ok, lets just assume this is a fact of life we have to deal with... How about using gdalwarp to create our resampled images one at a time (which we can do several in parallel) and using them as overviews? Can this be done? Is there a way to merge de resampled images into an .ovr? Or maybe reference the resampled images in a vrt and have them used as overviews? Appreciate any ideas on this. Thanks.
