The term 'map' has unfortunately turned into a generic one for all game levels but I believe old ben here means a literal picture or map of a completed track.
Firstly ben, you might check out the PDF packed inside rocketalces
Castle Nugget track, which is one of the most impressive and should read 'readmes' of any track (even if it is in that Pretty Danged Foul format). In that January 2005 edition of Moose Week magazine he included some nice maps based on Traxx screnshots if I'm not mistaken.
You can also make use of the <a href=http://mtm2.com/~trackville/gold.htm target=gold>Gold Mode</a> features to fly above your track and take screenshots of course.
But I suspect what you really want is what <a href=http://forum.mtm2.com/viewtopic.php?t=2615 target=tv>TrackView GL</a> can provide. Examples include almost every track preview shot on the download pages.
<a href=http://mtm2.com/~trackville/minimaps/tv2.htm target=wild>HERE</a> are some wide TVGL shots I took of the most highly developed terrain ever, and that doesn't even show the models.
Easy? Maybe not. All of these methods require some photo-paint skills to turn into a map.
