Taking the Train

It's not a complicated one, but I like Good Magazine's summary of the biggest train systems in the world (top 5 U.S. cities and top 5 foreign cities).  The silhouettes represent the daily rides in the city, and the length of the train shows how many miles that system covers.  To the right is a quick map of each city's subway system and some statistics about their subway system.

Space Debris video

Sticking with the Space Debris theme, the ESA (European Space Agency) has this hi-res video on their website showing how crowded Earth orbit has become from 1968-2000.  Same issue as the image yesterday, that the objects are not to scale.  At this scale you would expect constant collisions, but at actual scale you wouldn't be able to see any objects at all.

In this animation, catalogued space debris are shown accumulating around Earth in 4-year increments, including payloads, rocket bodies, and fragments. While the debris objects are not shown to scale, the representation of their density is accurate.

Space Debris image

Great image from MSNBC PhotoBlog that tries to demonstrate how much space junk we have put into orbit around Earth.  I think the downside of this image is that the satellites aren't to scale.  If they were all this large, they would be running into each other all the time.

If you have Windows, you can see this high-res version with Microsoft HDView, but it doesn't work on a Mac.  I was able to see it with Parallels running on my MacBook.

A computer-generated artist's impression released by the European Space Agency (ESA) depicts an approximation of 12,000 objects in orbit around the Earth.

One Month of Spam

From TimGraham.net, Tim plotted out some statistics about all of the spam email he received in February 2008. 

Tim, only 208.5 spam emails a day?  You need to get your email address out into more public places!

Thanks for the link Alwyn!

Mapping the Growth of Target

Nathan Yau over on FlowingData.com has done a great job creating an animated map showing the growth of Target stores across the U.S.

Well, fortune was smiling on me last week, and I got a hold of data for Target opening dates and locations (thnx, Cole). So here it is - a map that shows the growth of Target from 1962 through 2008.

Nathan has promised to combine the data from this map with his previous work mapping The Growth of WalMart, into one map where you can see the differences.  So we'll keep our eyes out for that.

Halo 3 HeatMaps

A while back Bungie.net, the makers of the Halo series of games, started tracking data on their servers about how their different online multiplayer maps are preforming.  They converted the data on kills and deaths in the multiplayer games into heatmaps, and then started publishing the maps online for everyone to see.

The advantages to players are that you can see places to avoid (areas with the highest deaths), and the locations from where the most kills come from.  The map above shows the total data for the map called The Pit.  But you can narrow down the information based on the type of weapon used.  For example the map below shows the locations of the kills made with the sniper rifle.  Meaning that shooting from these locations have been the most successful.  (Also helpful if you keep getting killed by snipers and can't find them)

"Heatmaps are the Doppler Radar System of Death in Halo 3. We're tracking encounters, weapons used and their results in a given game, collecting that data and sharing it with players visually. The key here is 'the darker the red, the more frequent the deaths (or kills, depending on the parameters)'," Bungie explains in its weekly update.

The Tallest Building: Burj Dubai

The Burj Dubai is a construction project to build the world's tallest building in Dubai.  Their website has a nice interactive comparison to the other key skyscrapers in the world.  The photo-like images on a black background with the reflection is very similar to the Apple Computer photo slideshows.

The goal of Burj Dubai is not simply to be the world's highest building.  It's to embody the world's highest aspirations.  Burj Dubai looks different depending on where you're standing.  For those living nearby, it is a shining accomplishment - tangible proof of Dubai's central role in a growing world.

Thanks Alwyn!

Immigration to the U.S. 1820-2007

Immigration to the US, 1820-2007 v2 from Ian Stevenson on Vimeo.

Cool video by Ian Stevenson (hosted on Vimeo) that animates the origins and number of people that immigrated to the U.S. every decade from 1820 to 2007.

Thanks Garrett for the link!

Ben Fry's Zipcode Project

Ben Fry is the author of Visualizing Data, and describes the ZipCode project in his book.  Each dot on the map is one zip code, and as you type a zip code, it highlights all of the dots that share that portion of the zip code.  You can turn on the "zoom" feature that zooms farther into the map for each digit you add.

This is built with the open source Processing tool that was recently released to the world as version 1.0.

Here are all of the zip codes that start with "6"

The Species-Scape

Christopher Taylor posted this image on his Catalogue of Organisms blog, and it has raised a little controversey about the details.  The intent is that the relative size of each organism in the image is representative of the number of species in that group.  So the large fly represents the huge number of insect species.  Towards that intent, I believe the image succeeds, but I have read some disagreement about the specific numbers used to develop the image.

In case you're wondering where the mammals are, we're represented by the reindeer cowering underneath the mushroom.

Two very similar images with some differences are also available.  One from the University of Sydney:

And another on from Cornell University: (this link wasn't working for me)

No matter which is exactly correct (and there's no way to tell), you get the point how small number of species of mammals are compared to the others.
