 There are some special landclasses, for instance the runway, the taxiways and the airport keep. They have dedicated effects assigned to them which (among other things) render them in especially high resolution since these are terrain parts one usually sees from close-up. Like everything else, they can be regionalized, but <i>do not mix their effects with the standard terrain effects!</i> It may seem tempting to use the airport keep effect also for other grass surfaces, or to render the airport keep as a normal landclass, but this will have unexpected side effects as soon as the terrain is drawn e.g. snowy or wet.
+=== Special situations ===
+A few extras may be considered:
+* ALS supports dynamical autumn coloring. Which part of a texture are vegetation and color reddish in fall is encoded in the texture alpha channel. Currently (April 2016) this is fully worked out for Europe, not for other parts of the world. For a good effect, this has to be done consistently for all materials as well as for the tree sheets themselves.
+* The color of both coastal areas and (in ALS) inland waters is determined at high shader quality by the global water depth map <b>/Textures/Globe/ocean_depth_1.png</b>. In coastal areas, the color encodes the seafloor color and the alpha channel depth, for inland waters the color directly affects water color. Do any modification to the depth map with care!
