Address Is Approximate 1

Address Is Approximate

A sweet piece of art, wonderfully executed (and using Street View) – enjoy it in full screen:   (Head over to Vimeo, if the embedded version doesn’t work for you. It often doesn’t for me.) The film was made by Tom Jenkins at The Theory film production...


What your map projection says about you

Today’s xkcd features a sociology of map projections. Hilarious! :) Mercator? You’re not really into maps. Take that, Google, Bing, Yahoo, Mapquest, …! PS if you’re not an xkcd regular: Don’t miss the mouseover caption.

Terminology is a beast: The many names of visualization 1

Terminology is a beast: The many names of visualization

Nathan Yau of Flowing Data has a blogpost about the many terms floating around visualization. It’s worth reading! But, in my opinion, not complete without Robert Kosara’s sometimes constrasting view. Terminology is often flourishing in thriving disciplines where people seek to differentiate themselves and find their...

A tale of times long gone

 See the wide channel that runs from left to right with the windy river in it? You are looking at one of the most amazing stories in geological history ever. I’d like to tell you about it. Over on Scienceblogs, Greg Laden has a great...

“What was there” project: More geocoded old photographs

While the news on Historypin is still fresh, the next project made its way onto my radar. Like Historypin, the “What was there” project crowdsources photos from times past and has them geocoded by users/contributors a.k.a. produsers. You can browse the collection on their website...
