Hi Mathieu,
Thanks for the clarification about Mobile Data Converter. I use QGIS. I tried the QgisODK tool but it appears that you need to generate your ODK collect form through this tool in order to download the polygons...(?) I think. Anyway, it gives me an error as soon as I try to connect to my aggregate...
I am wondering how all other users using the geotracing tool are now downloading or visualising their polygon data... As the geotrace/geoshape tool is quiet important for many users, I think it is quiet urgent to have something userfriendly to download the polygon data in user friendly format...
