Thanks Benni
Such tool can be handy in various situations. For the Mali activation,in 2013, we used Kuona, a similar tool, to locate the villages of north Mali. This large semi-desertic territory is flooded at rainy season and mappers had often missed detecting villages from imagery. The tool helped us rapidly locate residential areas and re-evaluate the situation. 

Quality of images often vary + Interpretation from the various contributors. Surely an aspect that you can analyze.

Dear Tylor, Dear Pierre,

thank you for your comments.

I added some additional information to the description of the pyBossa
task and also indicated that it is part of an acasdemic study.

Since we just started our analysis, it is maybe to early to discuss the
results. Nevertheless, it is good to know that there are other studies
regarding the quality of OSM data. Once we get the first results, I will
definitely have a closer look at what the guys from are doing.

Kind regards,
