hi to all
I have this goal:
I manage a participatory research on a place, people who pass can use an enketo form of which they find the indications.
Within this form they must also enter the GPS position where they make an observation and describe the place where they made it and leave a predetermined signal with a code.
Researchers have a control form where they go to the site and add details to the observations of the previous form.
The first form for ordinary citizens is used in enketo, and we know what the problems are in entering the GPS position with good accuracy.
I wish the researchers in their control form could verify the GPS position and improve it, as they use odkcollect.
But if I add such a line
type: geopoint
name: C_location
label: location
appeareance: Placement-map
calculation: instance(‘first_form’)/root/data[P_id = current()/…/C_id]/P_location
non-GPS position changes are not made.
The only possibility is to make an additional GPS point field?
Or the technique is to use the string calculation in “default”
Thank you
