Images of the world. Big images. “An original Russian satellite image from SPIN-2, for example, is a 40-kilometer by 160-kilometer sized photographic swath of a particular area of earth… The files Microsoft receives still contain too much data to be effectively downloaded over the Internet. Depending on the type of image — satellite or aerial photograph — a single image can range between 50 MB and 1,500 MB in size. The TerraServer team wrote an image processing program that takes several of these large input files at a time, computes the image’s location on earth, and merges pixels from multiple files into one single photo. The merged images are then cut into smaller images and compressed in the JPEG file format so Web browsers can recognize them.”
