Plateau augmentation factor could be improved to overcome striped patterns

[eoudejans]

The current augmentation factor for suitabilities is taken as: id modulo 1024:

attribute<int32> plateau_augmentation_factor (domain) := int32(mod(uint32(id(domain)), uint32(pow(2f,10f))));

This leads to striped patterns as the plateaus are lowered by factor 1024 in this case.

[eoudejans]

One way to deal with these stripes is to improve the plateau augmentation factor.

possible solutions:

• use rnd_permutation on compacted_domain
• augment suitabilities with "pseudo random" term (ID(.) jprime) mod 2^10 where j is the land use type.
