GPS and ODK Collect field surveys in Senegal since 2018, FTTH deployment plans in QGIS at Serfim T.I.C. from 2025 to 2026: I know how data is collected in the field and what it has to become in your GIS.
Health, research and open-mapping projects with ENDA Santé, the IRD and HOT; more than six months of continuous FTTH production in the Haut-Doubs; and a published pilot study on the flood exposure of the public car parks of Bernis, France.
Open formats (GeoPackage, Shapefile, GeoJSON), a QGIS project ready to reopen, sources, date and scale on every map. On request, I train your staff or field teams in QGIS, OpenStreetMap or mobile data collection, in English or French, with Fula or Wolof for field teams.
