ZMP

There are only two of these files in the World of Warcraft MPQs (they are also located in patch.mpq). They are located inside "interface.mpq\Interface\WorldMap\NNN.zmp". The NNN may be replaced with either "Azeroth" or "Kalimdor". These files are probably used somehow in loading the world map interface in the game. The code to read these files is also probably located within one of the interface.mpq files. These files seem to hold tile data (as the WoWEmu program uses them to extract tile data to output a rough hightmap of the world). Anyway, this would seem to be very logical, because ZMP would stand for Z-Map (Z, of which is the hight axis in 3D).

It appears that ZMP files are a 128x128 array of 32-bit integer height values.

+++ note from wad: all data in these files is location_id's (see:AreaTable.dbc).
