Hi Sergio,

thanks for raising this.

For the GIS app, we do in fact not base the thematic mapping on event
coordinates at all. In later versions you can render aggregated data from
program-based data elements as thematic layers, however that aggregation is
based on the org unit (e.g. facility) of the events, not the coordinates.

However, for the event layer, we do of course render events based on the
event coordinates. We have been thinking about supporting a an option in
GIS where you could base the clustering on the coordinate of the org unit
(facility) instead of the event itself. This makes sense and will not be
very hard to do. Blueprint for 2.25 here:

https://blueprints.launchpad.net/dhis2/+spec/event-analytics-clustering-based-on-org-unit-coordinates

Note that in my mind this really only makes sense for clustering of events
- for rendering of non-clustered events, you will basically end up with one
single point hiding a large number of points at the location of the
facility ;)

Let me know if this makes sense to you.

best regards,

Lars
