However, by having space and time asorthogonal dimensions, Time Geography requires the absolute view of space and time. ... representation). Space and time are joined in asingle space- time path. Space and time are considered inseparable within a path, and it is the timing component which gives structure to space and thus ... between the absolute and relative views of space and time can be devised in GIS. Besides, the whole rationale of the Time Geography approach is the inseparability of space and time. In otherwords,...
