Today I’ve found some interesting sources for vector data:
The first one: a vegetation classification of Gilford Pinchot National Forest:
I will have to process it to use it as autogen (what kind of trees and all that stuff). As far I can see the main class is Hemlock trees. There is no a lot of diversity.
I’ve found information about streets and roads from openstreetmaps and USGS but I haven’t checked them yet. I will use it to generate a mask in photoshop for the nocturnal texture. In this way I will gain an extra time generating that variation.
The downside of the day: I have not found yet any hangars reference, so I’m afraid that I will have to create “an interpretation” of them.
