摘要
针对当前时空数据管理中存在的主要问题,本文提出用PostgreSQL作为平台来进行时空数据的管理。本文从PostgreSQL自身的特点出发,并结合"香港18个地区区议会选举"的例子,分析、探讨了如何在PostgreSQL的环境中实现对时空数据的有效管理。并在此基础上,对时空数据的合理组织进行了研究,为时空数据的管理提供了新的思路。
Aiming at the main problems of current spatiotemporal data management, through PostgreSQL to manage the spatiotemporal data is proposed in this paper. Starting from the characteristics of PostgreSQL itself, combining with the example of ＂Hong Kong 18 Districts Council Election＂, analyze and further discuss how to efficiently realize the management of the spatiotemporal data in PostgreSQL Environment. Based on this, reasonable organization of spatiotemporal data is studied in this paper, providing new thoughts for the management of spatiotemporal data.
