| 英文摘要 | What we are now facing is the dilemma when we try to integrate Digital Cartographic Model (DCM), which is symbol-oriented model, and Digital Landscape Model (DLM), which is the geographical entity and topology oriented model. Basic theory of map modeling method of geographical data is researched. A new type of digital map data model is raised out and designed, including four levels as conceptual, logical, and physical model to satisfy visualization and spatial analysis at the same time. The formation of the digital map logic model relies on abstracting and summarizing the world by means of the object-oriented method, putting forward the conceptual model of the object-oriented digital map according to the OGC abstract norm, dwelling on all the kinds of objects in the model and logical design in which spatial data, attribute data, symbols, and topology are all stored in relational database, in form of various but inter-linked relational tabulations as point, tine, area, label, symbol, etc. And meanwhile, the author develops the data-modeling tool which turns the storage of the digital map in the relational database management system into realities, thus realizes digital map storage and manages in Microsoft SQL Server. |
