A very similar presentation was made in year 2014 by Dr.Paul Rosen at Victor Menezes Auditorium, IIT Bombay. At the end of that talk, Dr.Paul Rosen zoomed into the Powai Lake on the screen on Google Maps and said "We are somewhere here, right?". Of course, the presentation is brilliant in its all encompassing terrain measurements. I really appreciate such lectures and such technology is most exciting to work on.
