GIS for Public Health

India has very good Satellite Images and Geospatial Data for GIS. For public health the need is to layer the disease prevalence and disease trends on to the satellite images. ISRO, PHFI and a IT company with GIS and DW/BI capability should join hands in a PPP model to build the online Epidemiology model for India. CDC has tried to do this in US but the relevant medical data is scarce due to data privacy and business interests. Whereas in India the GOI and Stat Govt own the healthcare data. Also the private sector can be forced to share the medical data for epidemiological analytics. The need is for someone to take a lead. In my mind the lead has to be taken by the Govt.
