Warin, I’ve added the information about tracks in National Parks to the “track” description. Thanks for your input on this. It had clearly escaped me.

About paved/unpaved: Throughout the whole article I several times stress the fact that a road’s physical surface is not at all an sufficient indicator of it’s category. I do believe, however, that the surface can give a first hint to the importance of a road. In the West, you will find almost every road tarmaced, even the smallest one. But in Africa usually only the more important roads will have a sealed surface. So clearly the surface can give some help in coming to an assessment. This is why I would like to keep the surface references in the classification part.

Having said this, I deliberately added the picture from South Sudan to raise awareness about the fact that paved/unpaved alone is highly insufficient for category evaluation.

Hey Warin, thank for your appreciation and the helpful comments. I have added the information about unclassified roads in urban areas as well as adjusted the wording about the use of tracktype=*. I fail to see, however, why my description implies that tracks must be paved. This is of course not at all the case. Thank you again for your critical reading and your input.

No, this is not an import. As I said, the website had drawn my attention to the subject matter but I researched the office locations myself. So no need to be worried. :-)
