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. |

<p> |
|
17 |
<a name="OwnershipInfo">Owner values</a> <tt>00</tt> through <tt>07</tt> are companies (they're indices into the <a href="#_CompanyArray">array of companies</a>), <tt>10</tt> is no owner, <tt>11</tt> appears to be reserved for water, <tt>80</tt> and above are towns (in this case the low 7 bits contain an index into the <a href="#_TownArray">town array</a>). |

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