Hi Joseph, I've been cleaning up some of the Africover, mostly bound within the DRC borders.
The import seems to have been fairly messy. <snip> > There is no source tag on the data that exists, only an AUTO_ID tag; > an example way can be seen in 37424303 [3], although many more exist. > I'm guessing that the AUTO_ID refers to a Africover reference system > that has survived the import, whilst OSM specific tags need to be > applied. > > Is there any reference available for telling what such ways should be > tagged as?

The AUTO_ID is now worthless data to have in the OSM system, we have moved on from the original import. I'd say add source=Africover on the ways if you like. Best to strip it on nodes. The amount of GPS (GPX) data coverage is improving, especially in Southern Africa, so always compare. I always give existing data preference over Africover. If the Africover data feels VERY wrong, I think it is best to remove it rather than disrupt future (local) mapping efforts. Some of the ways also seem to be railways. Many Central & East African railways are being revived due to renewed interest in Africa's mineral wealth and Chinese interest. I tag with brain activated :-) Even Landsat helps. Some major African cities do have Yahoo! aerial imagery.
