My point this time is not the classification of a few roads. What I
learn from this, is that our data is processed and reviewed again. If a
mapping error is detected by local staff, it will most likely only be
reported to their own mapping department. It will also only be fixed
locally. We as mappers or validators will never learn from this process.
All errors will remain in the OSM Database. That might be understandable
in an emergency situation like now. But without direct feedback from
map users we will never improve. We should also demand that more local
knowledge will be shared with OSM. A simple thank you is not enough.

There is another wiki guide
https://wiki.openstreetmap.org/wiki/Highway_Tag_Africa
both get updated from time to time. As a general rule of thumb I tag
highways between settlements as unclassified not track, I leave it to
the local mappers to say if it is a higher classification.
Occasionally I'll tag as high as tertiary. Normally I leave the tags
alone but have been known to retag motorways between two small
settlements as unclassified.
I think step one is to get something mapped. Step two is correct it
and with lots of new mappers with different ideas we'll always see
some problems.

Hello Ralf
you pinpoint to a situation which is not always clear.
First of all. we ty to keep ourselves to the East African Highway
tagging wiki
https://wiki.openstreetmap.org/wiki/East_Africa_Tagging_Guidelines
Different mappers judge different how to tag a highway. Out of my own
experience lots of mappers (and validators) struggle with how to tag
a highway. Looking to the importance, the routing, and the width of
the highway, which is hard to measure from a satellite image, we have
to decide. A big number of new mappers are joining us and have
different ideas (nor no idea at all) how to tag a highway. I've seen
taggings as secondary highway as a connection to 2 hamlets and so on.
So we try to tag as good as possible, but often it is a
(calculated)guess which tag is relevant. Take also in account that
there is a huge time pressure on these disaster mapping projects, so
sometimes you accept the tagging as they were made. When there is no
time pressure you can take a look to each highway and decide.
I hope you get an understanding how we have to deal with this subject.
Best regards

Interesting when compared to the openstreetmap data.
There are many POIs I would like to see on Openstreetmap too, also
boundarys and place names.
I also noticed a different tagging scheme: Car, Moto and Foot. I would
guess that Roads not passable for a car but by foot and moto should be
highway=path in OSM.
But most of them are still tagged as unclassified or residential. Is
there a reason for that or will you change them later?
