| Abstract(in English) | Four dimensional data are defined here as the data specifed by a set of three spatial coordinate values and time coordinate value. An instance of the four dimensional data is a figure of 4 degrees of freedom in the four dimensional space. To give a spatial representation of such a figure and store it in the spatial database, a four dimensional spatial data structure is designed. In this representation, four dimensional data are modelled with simplicial complexes. For such spatial representation, set theoretic operations union, intersection, and difference geometric operations projection and cross section, and spatial predicates disjoint, equal and overlap are also designed. |
