By MARK SILVA CHICAGO TRIBUNE Jan. 31, 2009, 5:34PM WASHINGTON — Dick Cheney may not have lived in an undisclosed location while he was vice president, but it was all but impossible to see it on Google. Once obscured by pixilation, Google Earth’s image of the vice-presidential residence on the grounds of the U.S. Naval Observatory in Washington is now nearly as clear as its view of the White House. This appears to be none of the White House’s doing, however, even though the arrival of clarity coincided with the inauguration of the home’s new occupant, Vice President Joe Biden. “Google Earth and Google Maps are regularly updated as new imagery becomes available,” a Google representative said last week. “Our most recent update included updated imagery of the Washington, D.C., area from several providers.” Google’s aerial images come from third-party suppliers, the spokeswoman said — “some of which may blur images before they provide them to Google.” The old, pixilated view of the observatory grounds came from the U.S. Geological Survey, Google said at the time. Thank another aerial-mapping company, Digital Globe, for the clearer view. Built in 1893 on a hilltop in northwest Washington, The Naval Observatory has been official home to vice presidents since 1977.
