For the last few decades, reviews of the state of population geography have been provided seemingly every ten years (e.g. Findlay and Graham, 1991), often highlighting the advances within the sub-discipline and offering some fruitful ways forward. In this panel session, invited contributors will consider […]

Continue reading »Doug Fritz of the Google Data Arts Team shared a couple of lines about the project: ”Thanks to WebGL, we’re able to display thousands of moving points at high frame rates by using the user’s graphics processing unit (GPU) for 3D computations. Each state of the globe has its own geometry and we morph between them with a vertex shader, saving precious CPU resources. Additionally, to make the globe look nice, we took advantage of the possibilities of GLSL and created two fragment shaders, one to simulate the atmosphere and another to simulate frontal illumination of the planet”. So, here is what some Java script, and the latest technologies in open source (including WebGL and Html5!) can produce.
Latitude / longitude data spikes
Color gradients, based on data value or type
Mouse wheel to zoom
More features are under development…
