Models and queries in a spatiotemporal GIS

Baher El-Geresy and Christopher Jones

Much interest has been evidenced lately in the combined handling of spatial and temporal
information in large spatial databases. In GIS, as well as in other fields (Silva et al.,
1997), research has been accumulating on different aspects of spatio-temporal
representation and reasoning (Stock, 1997). The combined handling of spatio-temporal
information allows for more sophisticated application and utilisation of these systems.
Developing a Temporal GIS (TGIS) leads to a system which is capable of tracing and
analysing the changing states of study areas, storing historic geographic states and
anticipating future states. A TGIS can ultimately be used to understand the processes
causing geographic change and relate different processes to derive patterns in the data. read more
