Data Structure

Data Offset	Size	Description
0x00	Uint8	Width of Global Map
0x01	Uint8	Height of Global Map
0x04	Uint8	Number of Characters of Map Prefix
0x05	Char*	Map Prefix Name
Next	UInt16**	Data

* Length determined by 0x04

** Length of data is Height X Width

Data In Use

Let Height = 3, Width = 3, Data = ABCDEFGHI, Map Prefix = ExMap (so prefix length is 5)

[[A B C]
 [D E F]
 [G H I]]

This illustrates that the value at B goes with the map named ExMap00_01c because B is (0,1) in the above matrix. The map names are declared within the proper land_data[_release] files.

The value of B is the map value, that is, the value of the index of the map (where 411 is Twinleaf Town in DPPt and 60 is New Bark Town in HGSS).
