Should probably be posted/moved into the New Player discussion.

 

They also already have threads for things like this;

And even then, DayZ's Gamepedia Wiki and Interactive Map are the top results you get when you search for "DayZ Wiki" and "DayZ Map", so it's not like they're some hidden resources that no one can access. (And the wiki is fairly incomplete as of yet; there's a lot of outdated and/or misidentified information, and even more is just incomplete or has insufficient info.)
