Spatial Data Integrity In Spatial Information System

초록

This paper describes the design and implementation of an extended spatial query processing system, which provides integrity maintenance, security and knowledge representation in the spatial information system that manages the correlation between spatial data and aspatial data. GIS which models geographic and spatial information in the real world is implemented based on spatial information system. Spatial information system should handle data not as simple object but as abstracted complex object and maintain integrity for various derived data in the database system efficiently and represent the conceptual characteristic of spatial data as the format of the constraint. In this paper, we propose the spatial constraint language that can represent integrity information for spatial data as the format of the predicate logic in order to extend spatial query processor.
