Abstract:
The design of a spatial data warehouse depends on operational data, spatial and non spatial requirements in order to support the decision-making process required by final users. It is crucial to consider decision maker requirements in the conceptual level of the construction of a spatial data warehouse. Furthermore, updating a spatial data warehouse and especially the addition of a new user’s requirement after the construction of a spatial data warehouse is a great need for users. In this paper, to overcome this problem, dimension hierarchies will be specified in the Spatial Data Warehouse using topological relationships among spatial objects. Dimension hierarchies added show spatial requirements which are necessary to improve decision-making process. Decision makers thus will be able to achieve their information needs for analysis. Finally, we show the benefits of our approach by providing a case study, which defines an enriched conceptual model of a spatial data warehouse.
