I’m not sure that’s possible.
- The
geopoint
question can take any input at the XForm level, but Collect only allows inputting coordinates either by accessing the GPS/network location sensor of the device or the user selecting a point on a map. Enketo has these features and also allows users entering coordinates manually. - The
default
question type only allows values, no dynamic lookups (so ${location} won’t work as a default value) - KoBo’s map feature only works based on the first
geopoint
question it encounters.
Maybe @Xiphware has more creative ideas…
