A Beautiful Visualization

 Click the map to start the wind flowing*

Many years ago, Waldo Tobler provided the inspiration for mapping and modelling flows as potentials, possibly following Ravenstein, developing the simple concept of an ‘interaction wind’. His insight continues and now with new software like Processing we can visualize everything from Tweets in Manhattan to the Real Wind. Click through. Here is a link to one of Waldo’s early papers. You can see Ravenstein’s migration currents from one of Waldo’s maps which we reproduced on A Science of Cities website, here.

*(if the map doesn’t load, you may need a easy browser like Chrome)
