[Gdal-dev] how to calculate needed mem?

[Matt Wilkie]

Hi, is there a rule of them I can use to calculate how much memory will 
be needed for gdal_merge operations?

My current method of adding more tiles onto the input queue until I get 
"MemoryError: can't allocate memory for array" is a little wasteful and 
time consuming...

Or maybe it would be better to ask if there some way of doing things in 
pieces, not loading the complete extents into ram at one time?

thanks,
