I have shared my presentation from SOTM Africa here: https://drive.google.com/open?id=0B_2QVFnCIYvpQllEWnR2bWhTVnM
There are quite a few photographs of different types of roads in Africa along with the aerial view. At the workshop in Kampala there was a good deal of discussion and frustration expressed regarding inconsistencies in descriptions and usage. There was not a consensus that additional tags were needed, however, there was general agreement that the Africa Highway Tagging Guide needed some clarification. There was a suggestion that the editing software could have regional tag exclusions. An example would be highway=living_street, a legally defined type road that is not found in Africa. I like the guidance Bjoern gave us below and the nice presentation. My only suggestion would be that metal roofs could be one factor in determining path/residential/unclassified. I have seen many remote villages only accessible by path that have some metal roofs. I think the same could be true in Nepal? Here is a draft 1-page document for use in mapathons https://drive.google.com/open?id=1s0QB-B1MKqsRs51jyDsCuldEXsJ_xK17k0-kRyKmxoo <https://drive.google.com/open?id=0B_2QVFnCIYvpVW1xdHZ1RFF0dms> The order of tag listing is "upside down" emphasizing the most common routes first. highway=service should probably be added and primary could be dropped. Let's continue this conversation.
