"Every Monday morning, we will post a new map on this site. The maps will be unlabeled, uncaptioned thematic maps with no scales or legends.... For each week’s map, your job is simple: figure out what data is being presented by the map. To solve the map, you have to find the clues on it and come up with an explanation that ties them all together." [more inside]
Every cell of this grid contains the starting point to one of our journeys to Rome. Now that we have our 486,713 starting points we need to find out how we could reach Rome as our destination. For this we created a algorithm that calculates one route for every trip. The more often a single street segment is used, the stronger it is drawn on the map. The maps as outcome of this project is somewhere between information visualization and data art, unveiling mobility and a very large scale.Some beautiful and interesting visualizations of transportation models for Europe and the world, including all the towns called "Rome" in the United States. Also: Urban Mobility Fingerprints and Create Your Own (Europe Only).
What does a day's worth of activity look like for Boston's transportation system? Via bostonography, which has been featured previously.

The Great Firewall just got a little taller. Starting next month, all geo data about China must be stored on servers inside China. This is much more that a snub of Google for moving its data out of the mainland, it is a power play aimed at controlling a type of data about which China is very sensitive, as shown in recent border disputes, and the discovery of secret military installations.

The notebook of cartographer Zachary Forest Johnson. There is lots of good stuff here. For example, political cartography: voting with our pocketbooks, or this biography of Wild Bill Bunge.
The New York City Open Accessible Space Information System Cooperative (OASIS) is an online, interactive mapping and data analysis application that gives an incredibly detailed view of New York City's open spaces and how they are used. The map enables overlays of information like: transit; parks, playgrounds and open space; zoning and landmarks; current and historical land use; social services; demographics; and environmental characteristics.(via The Ministry of Type, who like OASIS mainly for its pretty map possibilities.)

Rents are up in San Francisco. CraigStatsSF can tell you by how much over the last year. (coming soon: NYC, Chicago, Toronto, Boston, and more. What neighborhoods are hot? (Heatmaps are cool). Firefox is your friend.
The before and after tsunami photos have been synced-up and they highlight even more (if that's possible) the power of the sea. Saomeone has geo-aligned the various before and after aerial and satellite photos and adjusted the scale to provide a very accurate then/now comparison.
A bunch of very beautiful Old Japanese Maps has been put online. Java application Insight(tm) required to view and includes a nifty GIS application to overlay old maps on current maps with 3-D animated fly-throughs. State of the art in online map presentation "The digital images are even better than the originals because you can amplify them, rotate them to look at them from different angles," Mr. Zhou said. "In practical terms, this is a better way of using the material than actually coming here to see the pieces."
Map enthusiasts might enjoy The Geography Network, a new venture from ESRI, vendor of the most used GIS system. The site includes an in-browser viewer, so you don't need to own any ESRI products to see the free data. If you do, though, the data's yours for the downloading. They've already got the latest TIGER census maps as well as a ton of maps and information from around the globe. They hope to create a central location for GIS data sharing, and they're off to a good start.
