Understanding just what is meant by "Smart City"

In my last post, I took a quick look at Smart Cities, I have had a long time research project going on this subject, collecting articles and general web pages, to try and understand just what is meant by Smart City, believe me when I say it's not a clear subject, there are a lot of variables, and differing opinions.

This video I have just come across, I think spells out a lot of my thoughts on the subject, interestingly one of the participants is the Ordinance Survey, OS, who I feel have a lot to give on this subject, from flood zones, paths, and marking interesting places and sights,

I will be continuing this research, because I don't think its solved yet, but I like what I see and hear in this short video.
