A paper-print panorama is always a compromise between field-of-view and detail. In the past I displayed the following image of the Adelaide central area as a 3 metre wide paper display, but that had logistic problems such as finding the wall space.
As an electronic display, only screen size is needed as wall space. Over time, all the detail in the image is displayed.
Only one source panoramic image is required. Software like Panolapse (http://www.panolapse360.com) can provide the sequence.
An electronic display also allows zoom.
