[HOT] West Africa Ebola Activation : follow-up

Hi Rafael,

this script look interesting, taking care to remove the tag and place it on a node.

Since there might be names around to reconcile with, this import cannot be done mecanically. 

There are some 4,500 of these places on polygons. To share this task among many contributors, I think that a good solution would be that the output of your script split the list of polygons + places, with a maximum  of 100 polygons / places per file, 

This way, the JOSM Todo plugin would let go rapidly through the list of place nodes, merge with an other place if appropriate and upload the result to the OSM database.

Is this make sense?

Hi, Pierre:

I wonder if you thought about replacing the names on the residential
polygons by a node in their centroid automatically using a script.

I created one for a similar task: the import of place names for
several states in North Nigeria, still a work in progress [1]. For that, I
wrote a script that extracts the names of the places and creates an
osm file with the nodes.

If needed, I can tweak the code to make one for this ebola task.
