Andrew and I did coordinate the Activation and passed some time around all of this area. We did everything possible working remotely to make the map. But there are limits to our mapping contribution. We cannot add local infos.
This is a great opportunity to have somebody like you and other people from the local community to complete the map adding POI and address names. We will be pleased to support your community. And as you saw working on Skype with Andrew, there are interesting ways to support at distance.
There was already some mapping done for Bo last year before the international community contributed to complete the coverage of Bo.
I agree with you Andrew, the building outlines are quite sketchy. It would be easy to erase / redraw. But I think that it is important to keep history of the work done before by local mappers. We should then avoid to erase / redraw the buildings.
We can prepare Task Manager Jobs to have the collaboration of the HOT-OSM community to revise the geometry of buildings and roads.
The Replace Geometry functionality in JOSM can be used to redraw rapidly the buildings. Adding instructions in the Task Manager, it should be easy for the contributors to follow the workflow using the Replace Geometry. I did a rapid test, moving the building aside, re-tracing it and then selecting the Replace Geometry to update it's geometry. It works fine. Revising highways should be easier.
For the Field work, we can provide you some learning material and support you in the first steps to update the map.

Thank you Alfred for introducing yourself to the mailing list and for
your interest in joining our community. Just to let everyone know,
Alfred and I spoke via skype last week and discussed his mapping of
the town of Bo. He has contributed hundreds of POI names and addresses
for the town already and is interested in further collaborating with
HOT in order to more effectively map the town. I suggested that he
post a message here to introduce himself and join the list so we could
discuss with the broader group how best to move forward in finishing
the map of the town.
As it currently stands, the town of Bo has most of the buildings
mapped (although they were apparently mapped from old imagery) as well
as most of the roads. This means the additional tracing work by our
remote volunteers could contribute is somewhat limited, but not
completely impossible to make further contributions. For example, the
imagery the buildings were traced from was mis-aligned according to
bing/gps traces in the area and also the building shapes are not quite
This situation means the mapping is a bit trickier than just working
from a blank slate, however I think it is an interesting opportunity
to test our skills on a more complete town as well as working out a
good workflow for integrating remote and on the ground mapping and
trying to find better ways of doing both.
I encourage others who are experienced mappers to have a look at the
town, how it is mapped so far, and to think about how we might move
forward from this point. Alfred is interested in doing more ground
surveys with his team, so I think we can have a really interesting mix
of local and remote participation and this could be a really good test
case for more detailed mapping.
I look forward to hearing what others on the list think about this
project and am excited to see how this will progress.
