I have come across a visualization technique called Here and There by Schulze and Webb from Alexis Kennedy (as ever thanks), other blogs and Wired Magazine (UK, June 2009). See below what it looks like:

As mentioned in Wired, it is like street view on a roller coaster – eye level and birds eye view. It is definitely innovative but it is not immediately clear what this gives above the “old world” of Google Maps and Google Earth. It is cool but what benefits can it offer - Some ideas that are suggested on S&W’s blog are:
- see through the city into the distance
- real-time activities like:
- traffic volume overlaid on the distant city map
- taxis or other services
- bottle necks
- all the things you can do with Google Earth / maps
All the same it is always nice to see a new way of visualising. Comments, thoughts and ideas would be appreciated!
