Hi Christoph, Frederik and all,

Thanks Christoph and Frederik for your two emails, two points related to
Benin :

Christoph, thanks for setting up that hosting and serving of 100% opendata
resources that we will be using in compliment of the freshly purchased
imagery over Cotonou for data creation in OSM. We will also be using it
locally in RS and this is a real add on for sure. Since 2012 with the
overall support of Frederic Moine (aka Fred cc'ed), drones have been used
in Haiti in crisis response (Sandy Haiti 2012) and in
development/preparedness contexte over Haiti by a collective of Haitian
dronistes also membres of OSM groups in Haiti (cc'ed Jean Presler aka Pres)
with some support of the International Organization Of Migration (IOM),
Drones Adventures, CartONG (Fred having designed and run a community drone
campaign support program for that French NGO) (1). Fred and the Haitian
dronists crew work has been pioneer in drone uses in real crisis response
work and at community level and held as a reference by domain experts
(UNOSAT etc, Fred can provide materials). This is what we are looking at
doing to fully address OSM imagery needs through 100% hyper high res
imagery in Western Africa via a South-South cooperation mechanisms allowing
Haitian and African to collect imagery via drones and map it jointly both
in Haiti and Africa. The connection already exists and in our last Togo
capacity building mission, we had a mapathon where by Western Africans
mapped Areas at risk in Port Au Prince (Haiti) tracing over an imagery
collected by the local Haitian droners and mappers (2,3). This
unfortunately requires funding we did not manage to secure yet and are
working on it. Purchasing imagery for OSM is one option at hand to boost
mapping in Cotonou via remote AND intensive field work done by Benin
mappers and partners in Academic, NGOs, Local Gov, Tech etc.

@Frederik, your point is well heard in Bénin where remote mapping will not
kill, nor demotivate, nor diminish field work, it will go hand in hand and
contribute to more efficiently use scarse voluntary or hyper small budget
resources and get more impact, enrich the map, grow the community and
enlarge the circle of partners + gain remote support from other Western
African groups and the overall global community.

Thanks for your two emails, apologies if any of the above clarification is
too long, I just felt details specific to the Benin were necessary at this

Excellent day to all
