Frank,
Thanks for the reply. I mistakenly said GeoRef when I meant to say
GeoTransform. Your description of what would happen if we make the
change confirms what we thought.
I think we will go ahead and make the change, and file a ticket. Lots

In fact, tiling the input or output won't help for the issue. The main
limitation of gdal_merge.py is that it ingests each input file in one gulp.
So the limit is on the dimensions of the input files. The buffer must hold in
RAM and be smaller than 2GB (the maximum size of a 32bit intege
Peder,
The problem here is the lack of or very large tiles/blocks in the image.
BandReadAsArray() was asked to read a whole 27989 x 62863 block into memory.
That's 1.76 Giga pixels. Too big.
Greg Coats' tiff file had tiles of 512 x 512 size.
Creating tiled tiffs is a good place to start. Use the

Its true that the grid is only slightly divergent from true north over
the width of the UK. However, we are stitching all the map tiles
together and need North to always be straight up the image.
I shall experiment with the gdal warp params suggest by Frank and see
how bad the warp is.

I want to run gdal_merge (and another program I made, based on gdal_merge) on
rather large files -- typically 3-7 Gbytes. Not surprisingly I run into
problems. I'm not very experienced in Python, but am I right to assume that the
error below probably is an indication on a size problem? What is t
