Logical Process Modeling of Spatio-Temporal Application
Aigong Xu · 2010
Geographical phenomena involve entities and changes that are located in both space and time. Therefore, it is not an unjust germane to declare each geographical phenomena as spatio-temporal phenomena. As a result of that, building taxonomy of spatio-temporal phenomena implies an analysis of the representation of facts and occurrences within a space-time framework. While the absolute approach represents the space-time framework as a set or a collection of points and time instances, the relative approach has a view of mutual relationships between real world entities for this purpose. Spatio-temporal models deal with this so called relative approach. Those are crucial for performing assumption and predictions for physical, environmental, space and biological science. Typical application examples include traffic monitoring, regional ozone monitoring, disease mapping and satellite data analyzing. This article addresses to the further development of Spatio-Temporal Process Model (STPM), which is from conceptual modeling phase up to logical modeling phase. This new model, which based upon concurrent processing and π-Calculus, stands for process oriented domain development and signal transmission between them. The logical modeling phase entirely
