<p class="MsoNormal">I am adding to the discussion of highway tagging in West
Africa. All of the projects that mapped highways in West Africa that I have
seen or been a part of followed the guidance of the Highway Tag Africa wiki
page (<a href="http://wiki.openstreetmap.org/wiki/Highway_Tag_Africa" target="_blank">http://wiki.openstreetmap.org/wiki/Highway_Tag_Africa</a>).</p><p class="MsoNormal">This past Spring I worked with some colleagues to create
this tracing guide (<a href="http://hotosm.github.io/tracing-guides/guide/liberia.html" target="_blank">http://hotosm.github.io/tracing-guides/guide/liberia.html</a>)
for mapping River Cress and Grand Gedeh Counties in West Africa. The tracing
guide was based on our interpretation of the Highway Tag Africa wiki page. This
tracing guide is quite good, and mappers appreciated the pictures and GIFs that
show examples.</p><p class="MsoNormal">When building the tracing guide I came to a few conclusions.
When reading the Highway Tag Africa wiki page I felt it have been wrong for me
to alter the instructions. It would have resulted in inconsistent tagging in
the region. I trust that a good amount of research and discussion has taken
place to get it to the point it is now.</p><p class="MsoNormal">- The guidance in the wiki could have been clearer. Although
I notice that is has improved since even a few months ago, there are now some
example pictures in there.</p><p class="MsoNormal">- It is difficult to teach someone how to classify highways.
There are eight types and often it is not clear when deciding between primary,
secondary, tertiary, and unclassified highways because the only difference
between them is the subjective size of the urban areas that are connected by
them.</p><p class="MsoNormal">- The unclassified road type was unintuitive the first time
I read the Highway Tag Africa wiki page. To me unclassified means something
that has no classification. Yet in the Highway Tag Africa wiki page it clearly
has a classification. I think the term ‘unclassified’ means something else in
other places though.</p><p class="MsoNormal">I think having pre-set tags available as a plugins to iD
editor should be a HOT goal, if it isn’t already. I don’t think we need there
to be a universal tagging set. People who set-up projects on the Tasking
manager could define the tags that fit best for the project. Although I think
it would be useful to further standardize some tags across many geographical
areas; it is important to maintain the flexibility for the geographical areas that
need unique tags.<u></u><u></u></p><p class="MsoNormal">Thanks,</p><div>Tom G</div>
