Hi Mip,
At the moment materials don't support this sort of automatic re-scaling, largely because it would make the texture calculation even slower. Thus, at present, you will need to manually rescale your texture image to ensure that the features are 'the right size' for your chosen horizontal scale and texture resolution.
For example, if I choose a horizontal scale of 1m and use a texture resolution of 4x, I know that each texture pixel will be 0.25m across. Hence, an aircraft runway that's 30m wide should have a width in the texture image of 120 pixels (30m / 0.25m/pixel = 120 pixels).
I'll have a thinker about adding auto-scaling to the dev plan for the next release. However, the chances are good that the results would look far worse than doing the rescaling yourself in Photoshop/GIMP/Paint.NET/etc before generating the texture.
Best regards,
Aaron.
