Watch: America's Mood, Visualized via Twitter

Twitterpulse

A group of researchers has attempted to visualize the mood of the nation over a 24-hour period using a cartogram mash-up of tweets and population data in Pulse of the Nation.

Mashable writes:

"Not only did they analyze the sentiments we collectively expressed in 300 million tweets over three years against a scholarly word list; these researchers also mashed up that data with information from the U.S. Census Bureau, the Google Maps API and more. What they ended up with was a fascinating visualization showing the pulse of our nation, our very moods as they fluctuate over time. The researchers have put this information into density-preserving cartograms, maps that take the volume of tweets into account when representing the land area. In other words, in areas where there are more tweets, those spots on the map will appear larger than they do in real life."

Tourists vs. Locals in NYC

Tourists

Here's an interesting graphic for you map and data lovers, based on geotagging Flickr data:

"Blue points on the map are pictures taken by locals (people who have taken pictures in this city dated over a range of a month or more). Red points are pictures taken by tourists (people who seem to be a local of a different city and who took pictures in this city for less than a month). Yellow points are pictures where it can't be determined whether or not the photographer was a tourist (because they haven't taken pictures anywhere for over a month). They are probably tourists but might just not post many pictures at all."

There's a whole set of them for various cities.

Map: The Gulf Oil Spill on Top of San Francisco, Rome, D.C.

Spill

Here's an interesting look at the size of the BP oil spill in the Gulf of Mexico in comparison with various metropolitan areas. A Google Earth API has been jiggered to layer a current image of the spill so its scope can be compared to places with which you might be familiar.

In related news, efforts to cap the leak in the Gulf failed over the weekend: "After the cofferdam was lowered onto the leak site, a slurry of methane crystals formed on the inside of the dome’s surface, making it bouyant and clogging the outtake at the dome’s roof. The giant box has been moved 200 meters from the disaster site, and is sitting on the sea bed. BP had anticipated that methane hydrates could form within the pipework from the dome to the surface, but not within the dome itself, especially at such a rapid rate."


The Most Comprehensive Map of Earth's Elevations Ever Published

Elevation

A new map from NASA offers the most complete view of elevations on Earth ever presented:

"The Global Digital Elevation Model was created using nearly 1.3 million images collected by a Japanese camera on board NASA's Terra spacecraft. It is made up of a giant grid of 23,000 tiles, with each height point spaced 98ft apart. It shows a detailed representation of the planet's land mass. In this colorized version, low elevations are purple, medium elevations are greens and yellows, and high elevations are orange, red and white. 'This is the most complete, consistent global digital elevation data yet made available to the world,' said NASA scientist Woody Turner. It is a large improvement on the previous best topographic map, where 80 per cent of the planet's landmass was surveyed during the Shuttle Radar Topography Mission."

The Earth as Facebook Sees It

A program that visualizes various types of Facebook activities by its users around the globe was developed by Jack Lindamood, Kevin Der and Dan Weatherford during a Facebook Hackathon event last month. Facebook is considering making the app official. Hackathons are events where programmers get together to collaborate and share ideas.
