<span style="font-weight: bold;"></span>Five arrays are used to encode the information of the contents of the tile.
<span style="font-weight: bold;"></span>Five attributes hold the information about a tile.
This can be seen in the <a href="landscape.html">Landscape</a> document. This page tries to give an overview of used and free bits of
the array so you can quickly see what is used and what is not.

<li><span style="font-weight: bold;"><span class="freebits">O</span></span> - bit is free</li>
<li><span style="font-weight: bold;">X</span> - bit is used</li>

<li><span style="font-weight: bold;"><span class="abuse">&nbsp;&nbsp;&nbsp;</span></span> - bit of attribute is abused for different purposes</li>
<li><b>NOTE: </b>counting the bits starts with bit0 in the most left position (eg. a bit screwed LE format; BIT by BIT) </li>
