GigaPixel Panoramas viewed in Google Maps - Genius
We wish we had thought of it ourselves, but the credit goes to Greg Downing and the team at XRez for using Google Maps to display high resolution images. By using a zoom lens and stitching software you can capture in scene in extremely high resolution - typically in excess of 95,000 by 40,000 pixels using a 300mm lens and 612 overlapping images.
If you then take the technology behind Google Maps and replace the maps with the resulting image you get a plugin free navigation tool.
The XRez site is well worth a visit...
