摘要
多比例尺空间数据库是社会和技术发展到一定阶段后对地理信息系统提出的必然要求,而嵌入式GIS由于其自身的特点,存储空间极度受限。因此如何在有限的存储空间条件下实现多比例尺空间信息集成成为我们研究的重点。针对这一问题提出了一种嵌入式GIS多比例尺多层次空间数据库模型,并通过试验验证了该空间数据库模型的正确性和可行性。
The multi-scale spatial database is the requirement of GIS when society and technology come to a stage. However, the storage space of the embedded GIS is extremely limited. So how to integrate the spatial data on the condition of limited storage space is becoming the focus of our research. Aiming at this problem, the paper provides a multi-scale and multi-layer spatial database structure in Embedded GIS. Experiments also prove that the spatial database structure is really valid and feasible.
