You create a structure similar to this:

You make boundary a Multiple (1:N) (Table layout) entity and coordinate a simple Coordinate attribute.

You can create a multiple entity “bountry”, with a single coordinate attribute. Collect Mobile doesn’t support coordinate attributes with multiplicity.

Hi Sandip,
in the latest version of Collect (3.12.24) there is even a polygon feature that can be helpful. What you will need to do is to: - define a calculated attribute (call it whatever you want, for example "boundary_polygon") - mark it as "Geometry" - define the expression to calculate the value as: geo:geometry(boundary/coordinate) - now the attribute will be available in the map view among the list of possible layers that you can add

Many thanks,
Open Foris Team
