Hi Natalie,

This is currently not supported, but sounds like an excellent feature. It
would be useful if you could file an issue on the issue tracking system (
jira.dhis2.org) and describe the use case in more detail.

Since DHIS2 now requires the use of PostGIS, I think there could be a
couple of work arounds.

1) You might consider to develop a custom JavaScript widget which would
perform this check for you.  (https://github.com/d3/d3-geo#geoContains)  on
the client.

2) A server side script could probably also check for this quite easily, to
at least identify if any points do not fall inside a given polygon using
the st_contains function of PostGIS.  (
https://gis.stackexchange.com/questions/222465/how-to-check-a-set-of-points-are-inside-a-polygon-or-not-in-postgis
)

Regards,
Jason
