Small map-editing question

Where are these extra terrain switches listed? Perhaps there are more? How did Gandalf find them?

Well, of course you can just try the next binary number on its own and just see what happens, but I do not think that the terrain-bitvector contains more than 11 significant bits to combine...

I think that I also recall that the 11th bit (1024) was only introduced later on with a patch - at least the map-editor did not list "many sites" in the beginning...
