Okay finished it all up.
You can download the autolevel application as follows.
http://www.bushtech.com.au/chads/AutoLever.exeComes with its own self installation program, and it pretty easy to install. After installation just double click on the exe file and you should be away.
Choose the .elv file of your terrian
Choose the .oba file of your terrian
hit go, and wait until its completed.
Go into your terrian and have a look around.
I suggest trying out a small map first to try out the application before trying it on your big maps.
Because i havent had time to edit the code correctly yet, it does take about 3 minutes to calculate everthing on big maps wiht 250 fields.
This should be fixed if the populatirty of this application increases.
