The film was assembled into a collection of discontinuous scenes (one segment per view per city block) and then transferred to laserdisc, the analog-video precursor to modern digital optical disc storage technologies such as DVDs. A database was made that correlated the layout of the video on the disc with the two-dimensional street plan. Thus linked, the user was able to choose an arbitrary path through the city; the only restrictions being the necessity to stay in the center of the street; move ten feet between steps; and view the street from one of the four orthogonal views.
