This flag determines how impassable the terrain behind cliffs is. Basically, the flag controls how far away from the edge of a cliff a structure has to be placed, or how near to the edge of a cliff a unit can move. This is done by changing the LandType of certain cells next to and behind cliffs to Rock. 2 is the only value that will work correctly, and even then the game will assume that all cliffs are 4 cells high.
