Could Fighting Global Warming Be Cheap and Free? →


So here’s what you need to know: Climate despair is all wrong. The idea that economic growth and climate action are incompatible may sound hardheaded and realistic, but it’s actually a fuzzy-minded misconception. If we ever get past the special interests and ideology that have blocked action to save the planet, we’ll find that it’s cheaper and easier than almost anyone imagines.

Very optimistic column by Paul Krugman. I have always hoped that investing in alternative energy sources also makes sense from an economic point of view, and Krugman points to some detailed studies such as the New Climate Economy Report that seem to support that.

Nobel Prize for the brain’s GPS discovery →

The Nobel Prize for physiology or medicine has been awarded to three scientists who discovered the brain’s “GPS system”. UK-based researcher Prof John O’Keefe as well as May-Britt Moser and Edvard Moser share the award. They discovered how the brain knows where we are and is able to navigate from one place to another.

I guess spatial is special after all.

TimeBliography →


TimeBliography by Willington Siabato (UPM) is a dynamic and online bibliography upon space and time in GIS. The bibliography is quite extensive (over 1300 papers) and well organized. It can be explored starting from any of the four main categories (core, secondary, others, and standards), by publication type (journal articles, book sections, etc.) or via free text search. Moreover, it offers the timeline view shown above that shows how the literature on this topic has developed over time. Definitely a very useful resource for anyone working in this area.

Location-Based Light Painting

Location-Based Light Painting from Philipp Schmitt on Vimeo.

Very cool project:

For any city, thousands of geotagged photos are available online. The project maps these photos in the places where they were taken.

A custom-built camera flash + smartphone setup queries the Flickr and Panoramio APIs for photos taken at the current geographical position. Whenever there’s a photo available, a flash is triggered.
Long-exposure photography captures multiple flash lights — each representing one geotagged photo — and situates them in the place of their origin.

Head over to the project page for more photos, process as well as technical details:
