摘要
首先简要介绍了ArcSDE技术及其在空间数据管理中的机制。然后着重描述了长江航道测量数据的管理现状和主要格式,以及实现建库后的测量数据建库管理流程,分析了系统的特点和优势。最后介绍了系统的逻辑结构设计和系统功能实现,并展望了航道测量数据建库的发展方向。
This paper firstly introduced the ArcSDE technology and the mechanism of ArcSDE for spatial data management. Secondly, the currentsituation of the management and the main format of the surveying data for Changjiang Waterway are described. A flow-chart for database management of surveying data is given, and the advantage of the database management system for spatial data of Changjiang channel surveying is proposed. At last, we proposed the logic structure design of the system and how to implement the system. Furthermore, the developmental direction of the channel surveying data management is discussed.
