Thanks. I attempted the layer method first, but ran into problems with the size of my images (map_c was pretty huge). Since then, though, I've transferred my work to a better computer with far more RAM.

But I think it's not an alignment problem. I will try the blur method you speak of. Plus, like I said, I know of some SRTM data anomolies on some of the northern islands, that I will have to address by hand.
