This map enhancement mod is a plugin and it needs a host mod to work. For this one, a host mod in the form of Atlas or Alphamap should do the trick. Here's the patch notes for this release:

v2.03.03
Magtheridon fix for non-english clients

v2.03.02
Fixed outland maps included with Atlas 1.8.6

v2.03.00
Support for AtlasExtras
Added search function (see 'Using AtlasLoot Search.txt' for limitation, etc)
Changed the way the minimap button is shown and hidden in an attempt to throw off addons that 'latch on' to the button and keep it shown.
Big Trad. Chinese update
Karazhan revamp
Huge Heroic Mode update
Added lvl60 Shaman PvP set for Alliance and lvl60 Paladin PvP set for horde
Updated lvl70 PvP reward prices
