After trying to find some more reflectance and rgb color data I came
to the conclusion that using reference photos and a couple of diffuse
values as guide is enough for povray because it is all done in simple
RGB color anyway.

Reference photos: http://www.corbis.com/professional/

Diffuse guide:
specular aluminum 0.95 
new snow          0.74 
concrete          0.40 
vegetation (mean) 0.25 
asphalt           0.07
