While being able to do a croase ground query on such a kind of regular grid might be beneficial for the weather module. I would prefer the ai module just using the already available bounding volume tree that is used for the main aircrafts elevation queries. This is already really fast. Also, may be making use of these bounding volume hierarchies for the weather module as an intermediate step might be a good idea?
