Giambattista Nolli’s 1748 map of Rome was a masterpiece: it was detailed, accurate and eschewed the prevailing “bird’s-eye” perspective for an overhead view. Researchers at the University of Oregon has put together a major web site on Nolli’s map, complete with background and research papers. Most notable, though, is its map engine, a Flash-based application that allows you to superimpose layers on Nolli’s map, with adjustable transparency. But the best part is the satellite layer: make it semitransparent and see just how well Nolli’s map holds up, 257 years later. Thanks again to peacay.
