    Wow. Your filter did a great job, and I'm sure that I can easily manipulate parts into another file as you mentioned, using layers in GIMP. But unfortunately you got sent a "bad" file to begin with- the grayscale is maxed out, so all the mountains look like plateaus, again. (Aka height clipping?) For some reason depending upon your settings on the Map-A-Planet site that happens sometimes, I've discovered.

    However, I have delved into the arcana of filesharing, if you'd like to see what I'm working on. I got a decent version from Map-A-Planet and re-did the histogram so all 256 grayscale's are used with white (255) defined as the highest point on the planet and others scaled down from there to black (0) being the lowest point on the planet. I've filled in a few of the holes in the data, but not all.

    The streaks are still there- I decided that just cloning looks like crap, so I re-started fixing the holes in the data by hand, and I'm far from done.

    I just realized that the file I'm working on is probably small enough to post here:

    Which is a bit disappointing, actually. I've clearly lost something. The original bitmaps are 13MB, but this is only 3.6MB. How did I lose all of that? And, indeed, if you look at my image it is much more "contoury."

    Grr. Well, I'm off to play around with this a bit more...
