I've thought it would be interesting for FlightGear/TerraGear to have
some sort of snow cover model that monitors weather conditions and
approximates snow fall, and then snow cover after that.  This could be
used in determining texture choices.

It would also be interesting to have some model for green up in the
spring and or fall colors and the transition to everything being
brown.  And of have this dependent on seasonal sunlight and
accumulated weather conditions.

For the usa you can get snow cover maps, and even satallite based
"green-up" maps.  It would be nice to some day get this all integrated
with FlightGear for either selecting which set of seasonal textures to
use, or perhaps doing some color tinting, or something like that ...

Just pondering ... any of this would be a long way over the horizon in
terms of my own todo list ...
