He posts here under the name of Kratzean. Why don't you PM him?
If your looking for particular help in getting started on putting the map together. Start a new thread and/or post what you're having trouble with. There are a few people here with mapping knowledge.
I know this wasn't the point of the thread, but XD What programs is that? I have it but I'm not sure where it's installed and it'd help if I could remember the name... and also, can you add blocks in it? (I have one program to do that with. No idea how to use it. It'd help if this one had that function o_o)
Edit: Oh, apparently it's BWSurveyor... but still, can it add blocks to a map somehow?
Edit 2: ... Nevermind again XD I'm figuring out how to use Eden Project. It's a little annoying but I'm used to interfaces like this, so meh.
OK so you are just starting in making xxx.lnd files.
There are a few rules you have to follow by the nature of the editors.
B&W Surveyor is the best there is.
It only works for 1 or 2 saves before tile lines become obvious.
No you can't add tiles just take them away but the lands you have to work with have enormous amounts of wasted space.
