Modeling and Implementation for Generic Spatio-Temporal Incorporated Information
초록
영어
An architectural framework is developed for integrating geospatial and temporal data with relational information from which a spatio-temporal data warehouse (STDW) system is built. In order to implement the STDW, a generic conceptual model was designed that accommodated six dimensions：spatial (map object), temporal (time), agent (contractor), management (e.g. planting) and tree species (specific species) that addressed the “where”, “when”, “who”, “what”, “why” and “how” (5W1H) of the STDW information, respectively. A formal algebraic notation was developed based on a triplet schema that corresponded with spatial, temporal, and relational data type objects. Spatial object structures and spatial operators (spatial selection, spatial projection, and spatial join) were defined and incorporated along with other database operators having interfaces via the generic model.
