I was talking about this very thing recently- apparently there are very few engineers with the experience to make decisions about certain major rail bridges- just two worldwide in one example. Experience cracks in such a bridge in UK and you have to fly one in from Japan- time and money wasted if all you have to do is stream data from a drone. If you need more detail add video/photo  data plus intuition from a local engineer's tablet or smartphone.

The real value-add comes when you ingest the rich metadata into a machine learning analytics platform like IDOL from Hewlett packard Enterprise. Combined with the Vertica Big Data Analytics Platform and you have cost-effective means of managing and insuring assets. 

Look at 360Globalnet for practical examples of utilising streamed data in insurance market.
