Spatio-Temporal Modeling of Dynamic Phenomena in GIS

By Saeed Nadi and Mahmoud R. Delavar


Although, most of phenomena change over time, there has been an attempt to model the phenomena of real world assuming a static nature for them. Even when changes occurred in the phenomena, it is restricted to identify and assess the changes over a period of time. These static modeling can be applied when phenomena with a long change period are considered. Since late 1980s, and by increasing geospatial information systems (GISs) applications, dynamic modeling has been highlighted. It is therefore led to the development of a GIS branch called spatio-temporal GIS parallel to temporal database management systems in computer sciences. Despite, most of current GIS analyses, which are based on static modeling, a growing number of researches in temporal GIS, are being performed, which may dominate GIS market in the near future. This paper investigates the principal concepts of space-time and other relevant parameters in a temporal GIS. Focusing on different temporal GIS modeling approaches, development of a prototype temporal GIS to simulate traffic information using a cadastral map at a scale of 1:500 are discussed
