I think we should take advantage of GNU Health integration with
OpenStreetMap , as we do with the Domiciliary Units and the DU surveys
for Dengue.
There is a nice link at OpenStreeMap GIS integration[1], that I hope
you find it interesting. 

To me, we should really take the advantage of the existing integration
of GNU Health with OpenStreetMap, to generate different
types of representation (health events, demographics, etc.. ) . This
also would allow cooperation with other organizations, such as OSM HOT
(Humanitarian OpenStreetMap Team)[2]

We would need an expert in the GIS area. I think Roberto knows a lot
about GIS, so please let us know your thoughts and advice.

Thank you for bringing up the idea ! I am creating a task for this, so
we can have the new module in Health 3.2


All the best
