[HOT] Why we fail mapping Ivory Coast ?

Political crisis following the presidential elections led to violence
all over the country :

* In Abidjan, number of displaced people was estimated to 800.000 two
weeks ago. Although calm slowly returns to Abidjan, violence is still
ongoing especially in the Yopougon district (west of the city, 1
million people).

* Violence has been terrible in the western part of the country. UNHCR
talking about "massacre" [1]. This area has been especially affected
[2] and the imagery we got yesterday from SPOT covers this.

* There are refugee camps in Liberia, approximately 150.000 Ivorian
refugees according to UNHCR [3]. UNOSAT has authorized OSM to trace
over one of its imagery for the Bahn camp in Liberia (the biggest camp
if I make no mistake) [4]

Unfortunately, the "end" of the political crisis does not
automatically implies the end of the humanitarian crisis : displaced
people will still stay in camps for a time, infrastructures are
destroyed, people are afraid of reprisals and violence. Protection,
health and food needs are big. Many organizations are now operating
there and lacking good baseline data.

As I told yesterday, OSM is in the Common Operational Dataset of OCHA
[5] : so OSM data is already used but needs to be improved

I know I am not good at summarizing the situation, many reports can be
found here for those interested :

> Hi,
> I have noticed that the participation in mapping Ivory Coast isn't huge.
> We usually have no data sources. So we spend time tracing with landsat, defining the areas of interest, trying to get images, and complaining about the lack of available data sources.
> For Ivory Coast we are in the contrary case : we have tons of satellite images but no one to trace over it.
> Perhaps you are currently mapping another area ?
> Perhaps you don't see the interest in mapping Ivory Coast ?
> Perhaps the data sources available were not promoted enough ?
> Perhaps quality of available satellite imagery is too bad ?
> Perhaps the communication around the usefulness of this mapping action wasn't good ?
> Perhaps the media did not talk a lot about this crisis ?
> Perhaps ... ?
> This is really a "naive" message, without pre-conceived ideas, just to understand why we fail and how we can improve.
> Thanks
