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]
The Map of Humanity [large .jpg] created by illustrator James Turner is an effort to describe the human condition in an incredibly detailed map containing thousands of names from history and fiction arranged in a theoretical geography that encompasses islands of Abandonment and Wisdom and regions of Abomination and Courage.
Oh, Inverted World. As we’ve all learned in school, 70% of the Earth’s surface is covered by water, only 30% is solid ground. What if everything was reversed? What if every land mass was a body of water, and vice versa?
The National Maritime Museum, Greenwich has some excellent online collections related to maritime history and technology, including telescopes, marine chronometers, sundials, and a whole lot more. Some stuff I've been looking at: John Harrison's chronometers (described in Dava Sobel's book Longitude), polyhedral sundials, and pocket globes.
