His first work on geographical data was the BDIS (Base de données des initiatives solidaires: Solidarity initiatives database) in 2010 which is no more active. Two maps are proposed on socioeco.org website: ESS initiative (http://www.socioeco.org/carteessglobal_en.html) which is based on the first ESSGlobal protocol (established in 2012) and SSE solutions map (http://www.socioeco.org/solutions_en.html) gathering all geolocalized pages of socioeco.org.
