The traditional cinema's reliance on an establishing shot is similar to the concern within some schools of hypertext with knowing where one is within any particular hypertext, and serves much the same cognitive purpose as hypertext maps and overviews. Establishing shots also have significant narrative purpose, allowing a space to be defined or described with particular qualities, and this aspect is also exploited by writers (including hypertext authors) to establish a locale, milieu, or setting, and then to 'enter' this diegetic world. The difference between these two is that the former relies on a cognitive rationalisation (making space intelligible) and the latter a narrative one.
