UseOfGeoODK

Hi, all.
Can somebody please tell me about (or, provide me documentation) the use of the "Mapping" fonctionality of GeoODK?
In advance, thanks and regards.

GeoODK is derived from ODK but maintained separately. See http://geoodk.com/ for details.

You can learn about geo question types in ODK Collect at http://docs.opendatakit.org/form-widgets/#id162

Many thanks, @LN.
