Isochronic and Isogreenic (!) Maps

Mark Harrower did a great job collecting a wide range of different ways to visualize geographic processes on static maps. Here you can see the greatest Isochronic maps and temporal cartograms he founded.

And this here is my favorite one: the interactive London Tube map (by Tom Carden)

Well, now it’s common sense that time influences our space perceptions. But the talented Xiaoji Chen thought that maybe environmental concerns should distort our spatial perceptions too. So she did not only some isochronic maps for Paris (using different transport modes) but she also did the isogreenic maps for Paris that take carbon footprint into account for using different transport modes.

Many Eyes - How the same data set can tell different stories

Lately a lot of websites have been talking about a Brazilian researcher called Fernanda B. Viegas (nyt, cnn); She’s a young specialist in Visual Communication and together with Martin Wattenberg she created the site ManyEyes where people can share data bases and try a variety of forms to visualize data.

You can see a little demonstration of the site in a special Brazilian TED Talk

or a more complete one in a seminar at Stanford University (download).

Some interesting things available at the site:

• Word Tree for Text Analyses (10^th minute at TED video)
• Social networks visualizations
• A lot of databases
• All kinds of different ways to visualize data and check how others visualize them

Commuting Time Maps in Great Britain

How long it takes to travel between one particular place and every other place in Great Britain ? These guys here did a useful study to answer that.

This would be the Rail travel to get from Cambridge Station to every other station in the UK:

China's empty city

How sustainable can that be?



Thanks to Leonardo Monasterio

The best stats you've ever seen

A great "talk" of Hans Rosling showing powerful visualization.


Thanks Mark D. Hayward for the tip.

And here you can explore his dataset, or google's dataset here.

American recession told by unemployment numbers

Beautiful interactive map of vanishing employment across USA (here)

Running out of data?

We love when we get access to new databases (like Census, surveys, etc.). Right?
Now imagine an integrated censuses database of over one hundred countries! The Minnesota Population Center can help you with this megalomaniac database.

Take a look at their site: project 'Integrated Public Use Microdata Series'.

Have fun.

Portuguese Urban (historical) Cartography

Here you will find a lot of historical maps of cities colonized by the Portuguese. Great Archive!
