Hi,

The instructions for that project
(http://taches.francophonelibre.org/project/44) - "for very experienced
mappers" - asked to use "Bing as common geometrical reference (or other
imagery that was used for OSM mapping of these area)", as is generally
considered good practice in OSM mapping - unless you have good reasons
to know that you have a better reference (and also time to adjust
geometries).

Note that there is now a project to map damage from UAV 5 cm imagery, of
interest to the Government of Haiti who sent Fred there to fly Potentiel
3.0 (http://potentiel3-0.org) drones :

Best wishes,

Jean-Guilhem
