Census Dotmap

Dotmap

Brandon Martin-Anderson’s Census Dotmap plots every person counted in the 2010 Census as a single dot on the map. Which is to say that there are 308,450,225 dots on the map. Zoom in and see (though it’s not labelled and can be confusing to navigate at higher zooms). I suppose this is the demographic equivalent of the 1:1 map of Borges’s “On Exactitude in Science.” Via Boing Boing.

The Measure of Manhattan

Book cover: The Measure of Manhattan Another mapmaker is getting a book-length biography. The Measure of Manhattan, Marguerite Holloway’s biography of surveyor John Randel, Jr. (1787-1865), whose decade-long survey of the island of Manhattan was the basis for that city’s street grid, comes out in February. Via BLDGBLOG, who blurbed it: “Marguerite Holloway’s engaging survey takes us step by step through the challenges of obsolete land laws and outdated maps of an earlier metropolis, looking for—and finding—the future shape of this immeasurable city.” Buy at Amazon | publisher’s page

Google Maps for iPhone

As announced by AllThingsD shortly before it happened, Google Maps for iPhone was released last night. If you rely on Google’s extensive local search database, Street View or transit directions, downloading this app is a no-brainer. You will say, “At last!” and go get it. Here’s the App Store link.

Some caveats: there is no native iPad version. Both Engadget and Techcrunch point out that this is a get-the-essentials-out-the-door-now maps app: certain features you’d expect from the desktop or Android version (e.g., biking, indoor, offline maps) aren’t available. While it’s vector-based, it seems to me to be a little slower and less responsive than Apple’s native app.

And its interface is quite different from the Google-based maps app we saw on the iPhone prior to iOS 6: not only does it adopt the design language of other Google iOS apps, like Google+ and the iOS 6 YouTube app (which isn’t to my taste, but Google is running with it), but it puts things in different locations: transit, traffic and satellite imagery are obtained by pulling from the right; local info and Street View are on the bottom. Obtaining the 3D map is not at all obvious: it requires a two-finger drag explained here. Which is to say that you may need to get used to the changes. If you were hoping to get the old Maps app back, that’s not happening.
