Hi Pamond,

Jan can comment on the possibility/way of *hacking* his GIS app to display
the heat map you wanted.

But you can also do this:

1. Get all your polygons by level -
api/organisationUnits.geojson?level=OU_LEVEL
2. You can feed the polygons directly to Google map API
3. Since there could be multiple levels and polygons/boundaries based on
state, county, district... you need to be a little creative to implement
some kind of zoom-in/out effects
4. Get all tracker data through event api - loop through and generate
LatLng objects
5. Once you have a bunch of LatLng objects and feed them to a map, you can
just call google map's HeatMapLayer visualization.


---
Thank you,
Abyot.
