Who has not been dazzled and intrigued when lifting his gaze to the celestial vault on a clear, dark night? The spectacle of those fleeting and distant lights racks both our eyes and our brains. Is this star farther away than that one, or is it simply less luminous?

Nooblast Project inspired by the old days Noösphere concept. Visualization picks the real-time data from public APIs and calculates overall strength of signal (recent network buzz) for two given keywords. Some picked events have geolocation information, so they mapped on the globe in the exact points. The overall strength visualized around the globe as “noo”-cloud, the size of which reflects event streams and shaped by geotagged data, building light abstract visual structures-snapshots in space for each term. It explores abstract visual component of generated crowd sourced info streams as the visual connection attaching you to the pulse of planet.
NASA World Wind , an open-source virtual globe with stars and advanced atmosphere & sunlight effects A virtual globe is a 3D software model or representation of the Earth or another world.
Terrestrial globes are designed to be a to-scale representation of the world presenting without the geographic distortion of two-dimensional maps. According to Webster's English Dictionary , the word globe comes from the Latin root word globus , which means round like a ball of yarn. However, the idea of the is much, much older. Read on to learn about the whole story.
Introduction to Virtual Globes Virtual globes are rapidly becoming an easy and accessible way of finding, distributing and visualizing all sorts of data in a geographical context. The basis of this technology are the confluence of centuries of geometric and cartographic techniques, the increasing availability of previously limited satellite data in the public sphere, and the attractive 'virtual reality' of science fiction computer games and cinematography, all linked by some clever image compression techniques over the ever broadening bandwidth of the internet. Google Earth, NASA WorldWind and ESRI's ArcExplorer all allow the integration of a large amount of data over satellite image and terrain data.
The WebGL Globe is an open platform for geographic data visualization.
Today, Google announced the launch of a simple 3D visualization platform called the WebGL Globe . The open platform is designed to display large volumes of geographic data on top of a 3D virtual globe, inside your web browser. Google has provided a couple of examples: A visualization of a days worth of queries in Google Search . Spikes are coloured by language. Height represents the volume of queries from that location.
