Editing Surface tile

Surface Tiles are a way to use high resolution ground textures for a small local region, usually around a base. 

The earth is split into 2048 tiles in latitude and 4096 tiles in longitude.

The surface tiles in orbiter consist of two parts: The actual tile textures for the planet and the 
surface tile definition in the configuration file of a base. 



The syntax for a surface tile list is

<pre>
BEGIN_SURFTILELIST
<texturelevel> <tilenumberfrommeridian_positive_for_east> <tilenumberfromequator_positive_north> 1
END_SURFTILELIST
</pre>

The filenames for the textures follow a similar scheme: 

<pre>
<planet name>_<texture level>_<E/W><tile number in latitude>_<N/S><tile number in longitude>.dds
</pre>

The function for getting the tilenumber in latitude is:

<math>TN_lat = \frac{1024*latitude}{90}></math>

The function for getting the tilenumber in longitude is:

<math>TN_long = \frac{2048*longitude}{180}</math>

Each surface tile is roughly 5 x 5 km large.
