Sorry for that I was in mountain area with the student of UNOGA with
limited acces to internet and time.
If you do the a query over Grand Anse area http://osmose.openstreetmap.

of duplicate building.
So please include a strong validation or cleaning process after each
As is not acceptable to work like that and let all this mistake....
All the best FredM
