> That is fantastic! I am impressed, our maps look so much better with that background :-). Is there a special reason, that e.g. osma doesn't produce transparent tiles by default (we could than underlay those relief tiles as well)? That would make the output even prettier.

It depends on what exactly you want to do. For instance for the overlay
it would be better to not render forests, so they don't appear as large
green blobs when you can see much better that they are forests from the
sat images. There are so many different ways of arranging the existing
data for different uses.

My hack ist just that, a quick hack. I hope that somebody will produce
native Mapnik and/or Osmarender tiles with transparent background and
styles which go nicely with the sat images.
