Stephane, 

We need to filter points produced from the Crowdsource web application to retain only those for which we have not traced the residential area yet. We have to compare with residential areas already in the database. 

Some work has already been done. And the best is that you come and discuss with the contributors working on this on the hot irc.  Some the people working on this are Nicolas Alvarez, Andrew Buck, Pierre Giraud, Harry Wood.  They will be able to better answer about this.


 
Pierre

The first discussion was with the WASH coordination Cluster for water and sanitation. We have exchange about our experiences geolocating various infrastructures and ways to improve coordinattion eand exchange of information.

Nicolas Alvarez of HOT has proposed to use Crowsource of Imagery recognition for villages and dams and developped an application.  While this is still experimental, it gives very interesting results.  Pierre Giraud have adapted the Task Manager to accept Special micro-tasks defined from the result of this Crowdsource exercise. Instead of having contiguous micro-task tiles, we have tiles only where villages were detected.
