Five arrays are used to encode the information of the contents of each tile. These arrays are referred to as "< span style = "font-weight: bold;" > map_owner< / span > ", "< span style = "font-weight: bold;" > map2< / span > ", "< span style = "font-weight: bold;" > map3_lo|_hi< / span > ", "< span style = "font-weight: bold;" > map_type_and_height< / span > " and "< span style = "font-weight: bold;" > map5< / span > ". 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 < a href = "landscape_grid.html" > Landscape grid< / a > page.

OTTD's class-specific periodic tile processing routine is called once every +256 ticks for each tile.
