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.
