Using the railway network as a flatbed scanner

The author developed a technique using a linear scanning camera mounted on moving trains and ferries to capture extremely high-resolution panoramic images by capturing thin vertical lines of data as the vehicle moves, then stitching them together—similar to how industrial scanning backs work, but applied to landscape photography. The method, inspired by prior scanning camera projects, produces images with exceptional width-to-height ratios (such as a 56,894x2,048 pixel image) by treating the moving vehicle as a flatbed scanner.
