<h3><a name="Landscape">Landscape</a></h3>
<p>
Five attributes hold the information about a tile.
These attributes are referred to as
"<span style="font-weight: bold;">type_height</span>",
"<span style="font-weight: bold;">m1</span>",
"<span style="font-weight: bold;">m2</span>",
"<span style="font-weight: bold;">m3</span>",
"<span style="font-weight: bold;">m4</span>" and
"<span style="font-weight: bold;">m5</span>".
The most important value is the class of a tile, stored in the upper 4 bits of the type_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.

<p> Seven attributes (counting &quot;type_height&quot;) hold the informations
about a tile. These attributes are referred to as "<span style="font-weight: bold;">type_height</span>",
"<span style="font-weight: bold;">m1</span>", "<span style="font-weight: bold;">m2</span>",
"<span style="font-weight: bold;">m3</span>", "<span style="font-weight: bold;">m4</span>",

<p><a name="OwnershipInfo">The owner of a tile</a>, as frequently associated with attribute m1, can be either players (human or AI) or "Game entities".
They are identified using:
<ul>
<li>00 = current player</li>
<li>01..08 = AI or network players</li>
<li>0F = a town owns the tile</li>
<li>10 = nobody owns the tile</li>
