Five arrays are used to encode the information of the contents of each tile. These arrays are referred to as <a href="#_landscape1">map_owner</a>, <a href="#_landscape2">map2</a>, <a href="#_landscape3">map3_lo</a>, <a href="#_landscape4">type_and_height</a> and <a href="#_landscape5">map5</a>. 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.
