Having been impressed with Google’s steady introduction of their auto-generated 3D city meshes, I was equally surprised with Yell’s offering (above), which is the first of its kind for London. Powered by C3 Technologies the photo-realistic 3D maps are created from aerial film footage shot from light aeroplanes, which is then merged with other film taken from ground level. Unlike Google’s offering (below), this seems to produce a far more seamless effect as there is no obvious transition between aerial and plan projection. The result is a novel way to explore with the 3D map providing all sorts of otherwise unobtainable views and vistas.
