It is fairly easy to imagine incorporating standard temporal duration models to GIS as being a relatively straightforward task, but it is entirely much more difficult to imagine providing a GIS with the functionality to make the required spatial data measurements to implement spatial duration modelling. That is, since duration analysis was developed for temporal durations, various aspects of spatial durations such as direction or weights (magnitudes) are not typically a concern of standard statistical packages. Since temporal durations, by definition, have an implied ordering and directionality, existing statistical software is restricted in its functionality for spatial analysts. Routine statistical tests like the Log-Rank test for comparing survivor functions require weighted durations for their use in spatial duration modeling, but existing statistical software does not permit such functions. Thus, this information must be measured and incorporated into spatial duration analyses by user-written routines coupling existing GIS functionality with statistical software packages. Obviously, spatial duration research extends beyond purely technical concerns such as weighting observations, to the investigation of edge effects and determining the influence of a suite of spatially-varying variables on a spatial process, all of which become increasing complex to handle without suitable spatial analytical functionality in a GIS. The link between spatial point pattern analysis and spatial duration analysis should not be overlooked since this provides a new framework within which to conceive of spatial processes and to investigate such issues as spatial censoring, spatially-varying variables and spatial heterogeneity. Spatial analysts must look towards enabling future GIS to handle the special requirements of emerging fields such as spatial duration analysis, particularly since these methods are very suitable for an assortment of research in geography, regional science, and other disciplines that study the Earth's surface. GIS will make sophisticated spatial analysis tools accessible to more users, but at the same time spatial analytical advances must be facilitated by the development of GIS technology.
