This is a Flat Map generated by Undala (myself).
The statistics are as shown:

• Size - 2048x2048 blocks (128x128 chunks)
  
• Topsoil Material - Grass
  
• Underground material - Dirt
  
• Underground Depth - 32 blocks (excluding Adminium bottom layer)
  
  
• Adminium Bordering - Bottom Layer (no walls)
  
  

It's larger than the state of Delaware. IT SHOULD BE ENOUGH TO BUILD ON.

If walls are requested I will add them, but as long as you stay in the middle (which shouldn't be that hard to do) you won't generate any more map. The spawn point is set to the approximate, but not precise center of the map.

Enjoy, fellow craftsmen.
