This is downscaled version of a 800 megapixel original panorama. The view to the construction site was shot with a 50mm lens and the rest with a fisheye lens. These two panoramas were combined to offer a detailed view to progressing market square renovation site as well a full 360 degree view to the rest of the scene. Here's an earlier view from almost the same place, also there's some (low quality) cylindrical panoramas from the site itself on Kuopio.fi.
The full resolution spherical panorama is visible in my blog.
