Hi Pierre:
Thank you for the pointers to the 2013 discussions. I will look at the
archive.
I can tell you that from what I have seen on the ground, the Mali
activation is definitely a success, in particular if you compare the
level of details and accuracy with google maps.
I do like the approach of differentiating the road importance and its
condition as currently explained in the guidelines, and I think it works
well with the "Primary/Secondary/Tertiary" classification.
It appears some people in Senegal have raised the same issue about the
use of trunk, so I am going to follow up with them.
Regards,
Vincent Dawans

Hi Vincent,
Thanks to come and discuss about this. And I am pleased to have the
opportunity to discuss with you and have comments on how usefull are
those maps for road navigation. We dont have often some feedback from
people travelling in these areas and this is much appreciated. I am
also happy to see that you try to have local people to collect data
with GPS.
If we want to progress collectively on this, it's worth take time to
discuss before amending the wiki page. And it would be interesting
that some african contributors participate to such discussion. Other
HOT coordinators for various Activations might also have something to
say about this.
Note that you should find various discussions on the subject on the
Hot list in 2013.
We initiated the Mali_Highway_tag wiki page in early 2013 to help in
the context of the Mali Activation the remote mappers to classify the
highways in a more coherent approach.Thus, have the possibility to
deliver rapidly a more coherent road map with all the remote mappers
contributing to the classification.
At the time, we had various discussions on both the HOT irc and then
HOT discussion list. Later, some discussions suggested that such
classification was representative of Africa in general and the page
was renamed to Highway_Tag_Africa. As explained in the wiki page, we
thougth that it was important to make a difference between the
importance of the road and it's surface / condition.
It seems interesting to add the trunk and the motorway
classifications. Since we need other information then simply classify
from observation of the Imagery, I think that such categories should
be added in a clearly identified section of the wiki page, probably
with a color box. Then I suggest that instructions should be given
that these classifications are later added, once the roads have been
traced from Imagery. This should be done by experience mappers that
do have appropriate information about the road network. Ideally, this
step should always be done and had planned to do it for Mali. But we
often do not have people witth the local knowledge to revise the road
classification and adapt to the context of the country or region like
you propose. Plus we had a lot of Activations to take care in 2013.
It is surely welcome if you propose to revise the classification for
the major roads being part of theTrans-African Highway Network or others.
Regard
Pierre
