[Lucas2011]

Hi Guys i‘m new in this Forum.
Sry for my little bad english, because i‘m living in Germany

So i want to Start a Project in Minecraft on my own Server.
I want to Build the Maps from NfS Underground 1 and 2, Most Wanted 2005 and Carbon 1:1 in Minecraft.
Now here‘s my question: Does Anyone knows the Size (length and wide) of this Maps? I read, the Map of Underground 2 is 3.59 mi (In German are this 5,78 Kilometers) wide and 3.88 mi (in German are this 6,25 Kilometers) length.
