More than big data, there is an acute need of proper primary data where it is not available on public databases and proxy indicator driven data is incomplete at best.

Rather than depicting the right baseline, we are often more concerned with the analysis. We need start ups who would collect basic data first and then think about visualisation, and predictive analytics.

Any app yet to replace the field anthropologist to collect cold objective data from respondents for policy makers? Ofcourse remote sensing and GIS spatial analytics help a great deal.
