A screenshot of the new Mapply platform. For the interactive version, see http://www.mapply.com/
This is Mapply - Virtual 3-D Maps built with real world data. So far, the website just shows demos - the actual application is not really up and running yet, but the developers are claiming some amazing things for their platform. They say they have real-time data for 400 cities in 52 different countries, and there is practically no limit to what you can find with the data. There will be real-time data on weather, traffic, what's happening in each city, how to get around, connections to all kinds of data extracted from social media that will inform our understanding of a place, and more - all in one site for easy access. They say it will change the world!
