A few new Google Earth layers to tell you about. Data from several web communities — Wikipedia, Panoramio and the Google Earth Community — are also available in a new “Geographic Web” layer. The “London: A Life in Maps” exhibition, about which much has been posted (most recently here) also has a Google Earth layer. And the Rumsey maps layer (previously) is now available in non-English versions of Google Earth. And once I get my Intel iMac back from the shop (taps feet impatiently), I’ll be able to check these layers out properly; Google Earth doesn’t run nearly as well on my backup computer here (a G4 iMac).
