Bah I lost all my bookmarks, but there are very much higher resolutions available
freely on the net. You just have to keep looking. I remember seeing 100m resolution
for USA. Something less than that for ROTW. Some people even have cloud maps.
Lucky really that I can't tell you the URL, it would make it too easy ;)
