This is used for displaying the world map UI. Some zones (like draenei and boold elves starting zones in the current data files) are physically stored in a map (ADT, Expansion01) different from the map where they are shown on the world map UI (Azeroth / Kalimdor). Therefore in order to display zones, and likely player positions, correctly on the world map UI (global continent maps), their coordinates must be mapped from physical map to virtual map (add x and y offsets from this dbc to their position and then you can transform coordinates to display it on new map). When a virtual map is identified in WorldMapArea.dbc the data for transforming coordinates between the two maps is found here in WorldMapTransforms.dbc. - From Source Peek Wiki
