Hello,
We are implementing an Origin–Destination (OD) survey in KoboToolbox.
We uploaded a GeoJSON file with transport zone polygons via:
Form → Settings → Media.
We need enumerators in KoboCollect to select:
• Origin zone
• Destination zone
directly from the map (by clicking on the zone polygon).
However, currently the zones are only displayed on the map,
but they are not selectable in the form.
Is it possible to link GeoJSON polygons to a
select_one question so that enumerators can select a zone
from the map in KoboCollect?
If yes, what is the correct way to connect the GeoJSON file
to a select_one_from_file question?
Thank you in advance.
