-Five arrays are used to encode the information of the contents of each tile. These arrays are referred to as map_owner, map2, map3_lo, type_and_height and map5. The known encodings are listed in the table below. The most important value is the class of a tile, stored in the upper 4 bits of the type_and_height array. The lower 4 bits are used to encode the height and slope data. For a graphical represenation of the tile-layout have a look at Landscape grid page. +Five arrays are used to encode the information of the contents of each tile.

-Owner values 00 through 07 are companies (they're indices into the array of companies), 10 is no owner, 11 appears to be reserved for water, 80 and above are towns (in this case the low 7 bits contain an index into the town array). -
