摘要
空间数据引擎是实现空间数据库的核心。以空间数据引擎的标准与功能为分析起点,以其空间数据存储模型、图层管理为分析重点,并结合数据库管理系统与客户端应用程序,对空间数据库技术的理论体系进行了较为全面的论述。通过在"重庆市土壤信息系统"中的实现与应用,证明了空间数据库技术在土壤信息系统中运用的可行性。
Spatial Data Engine is the core technique to realize the spatial database. Started with the analysis of standard and function of SDE,appended importance upon the analysis of data storage model and map layer management of spatial data, and with the analysis of database management system and application program, discussed the theory system of spatial database comprehensively. Through the realization and application in Chongqing Soil Information System, the feasibility of the application of the technique of spatial database in soil information system was proved.
