In some rural areas people have a lot of different vehicles for transport. Some adapt motorbikes with cargo carriers making them into little trucks and motorbikes can be loaded in various ways and are used as transport, and these can travel on many tracks and minor/unclassified roads, so limiting to a certain size vehicle is putting too much of a restriction on mapping in Africa, in my opinion.

(A Land Rover's roughly 2m wide). There's a scale on JOSM and ID. Couldn't see one on Potlatch.

When Courtney and I created the Mozambique Tracing Guide the original tasks were urban focused, and the scope has changed to rural areas. Currently a group of interns are mapping those districts and I've had several inquiries about road classifications. The guidance I’ve given is to tag all rural roads as unclassified unless they are clearly labeled/numbered as a “major” road, or very small pathways. The Africa roads wiki is great and was referenced when creating the Mozambique guide. Many road examples in this part of the world are debatable as "unclassified", "tracks", or "paths". It’s almost impossible to know the use and in some cases classifications may change based on time of year. A subset of interns copied here (Forrest, Julia, and Alex) have agreed to review the Mozambique guidance and suggest edits for the rural landscape. This could be a good opportunity for them to review and comment on the Highway Tag Africa wiki as well. More to come.

The UK Ordnance Survey was historically important in creating everyday maps. By using a standardised set of tags for highways it makes the rendering systems life easier. OSMand for example is used everywhere in the world and if it had to know about a different set of tags for each country the software would be much more complicated. If you’re mapping in OSM of course there is nothing to stop you tagging highways in any manner you like. The only problem is that the features will not be rendered by the normal systems. If you’re mapping in a HOT project then you’re expected to follow the HOT guidelines for tagging. ie building=yes etc. The problem here is the instructions for a group of projects only contain a subset of the highway types used for mapping in Africa as defined by the African Highway Wiki and the examples shown are all urban areas so the instructions although correct are incomplete as the project covers both urban and rural areas.
