This terapixel visualization of Newcastle we computed recently on a cloud supercomputer using 128 Azure NVIDIA K80 GPU. It shows the city and sensed data about the city, one pixel in the image is equivalent to approx 1mmx1mm in the real world. Thanks to krpano we are able to make this available for anyone to browse on the web, it is hosted on Azure Blob storage and uses about 0.54 tB of storage, consisting of just over 5.5 million 512x512 pixel tiles.
