Grid corrections : places where North American roads deviate from their otherwise logical grid lines in order to account for the curvature of the Earth. You could drive out there your whole life, de Ruijter realized, and not realize that certain stop signs and intersections exist not because of eccentric real estate deals, but because they are mathematical devices used to help planners wrap a rectilinear planning scheme onto the surface of a spherical planet.
MeFi's own Alan Taylor brings us another crop of stunning aerial imagery from Google Earth, inviting you to guess what you're looking at. Now with multiple choice! (previously)
The official Google Earth plugin is one free download that makes all sorts of cool stuff possible in your browser. There's a full screen version of the program (complete with underwater views and 3D buildings) which can be searched by entering queries at the end of the URL. There's a framed version with support for layers, historical imagery, day/night cycles, and the Google Sky starmap. Less useful but more fun are Google's collection of "experiments" demonstrating the possibilities of the Earth API, including a "Geo Whiz" geography quiz, an antipode locater, a 3D first-person view of San Francisco, a virtual route-follower, and MONSTER MILKTRUCK!, a crazy fun driving simulator that lets you careen a virtual milk truck through the Googleplex campus, ricochet off the Himalayas, or explore any other place you care to name. Lots more can be found in the Google Earth Gallery -- highlights include a look at mountaintop removal mining, a real-time flight tracker, a guide to trails and outdoor recreation, a 360 panorama catalog, geotagged Panoramio photos, and the comprehensive crowdsourced Google Earth Community Layer. And while it's too large to view online, don't miss loading the Metafilter user location map into a desktop version of Google Earth! [more inside]
Fernando Vicente creates his own Body Worlds*, shows what makes people tick, gets under their skin, and appeals to dignity and prurience. Also, he has a blog. Reminds me of Boris Artzybasheff and Yoshitomo Nara for different reasons. via strange maps [more inside]
Discoveries made using satellite imagery, particularly via Google Earth, have made headlines in the blue and green before. Increasingly high-resolution photos, combined with obsessive interest, have lead inevitably to the next step: interpretation and analysis of spots on the Earth's surface for which information is restricted, censored, or classified, such as the preparedness of military defenses in North Korea and Iran, or the viability of Saudi Arabia's next big oil play. Of course, not all mapping is benevolent.
Samarra is in the news. The modern city is small, but built on the colossal ruins of the capital of the Abbasid Caliphate. Google Earth reveals amazing details of the ancient city, one of the largest archaeological sites in the world.
