GIS: Polygon layer under points

In many countries (I have a case right now) we will have a low
administrative boundary level (e.g. "villages"), where each village is
assigned to a health facility one level up. This means that there is
actually a point layer (facilities) above the lowest polygon layer. I
suppose clicking on a facility (drill-down) should display the village
polygons assigned to it - but I don't think we are able to handle that
currently?

Are these villages part of the org hierarchy in DHIS and actually collect data?
I guess the villages could also have a parent polygon level (subdistrict or similar)?

<On Topic>

I suppose this is akin to "communities" as well, where community
health workers may have a certain area which they work in, but then
report data to a facility. I agree, it is a valid use case.

Not to distract too much from this thread, but I think it point to the
need for a blueprint on how the GIS interacts with the hierarchy.

In Nigeria, we have GIS data for states, local government areas (LGA)
and for some facilities (as points). What we do not have geodata for
is the ward level which is in between the LGA and facilities.
Effectively, one would need to "drill-through" the ward level, as
there is no geodata there (yet) and may not be.

The last level of the hierarchy is a service delivery point (SDP) ,
which is effectively a unit within a facility. Again, this level has
no geographical data, but is still present in the hierarchy.

In this case, ideally, we would limit the orgunit levels available to
map, to those which have data (province, LGA, facility) and exlcude
those which do not (ward, SDP)
