摘要
自数字国土工程建设以来,土地信息系统是其中重要部分,从最初的数据库建立发展到现在综合应用平台。本文对目前土地信息系统建设情况进行总结,同时对建设过程中出现的问题进行分析,找出造成这些问题的原因。从多个来源的空间数据收集和更新、空间数据库建设和管理以及整个系统的结构这几个方面介绍了土地信息系统建设的技术要点及其解决方案。结合当今社会信息化的新形势提出了土地信息系统朝智能化、三维化、平台化的方向发展的趋势。
Since the construction of the digital land project,the land information system has been an important part,developing from the initial database establishment to the current comprehensive application platform.This article summarizes the current situation of land information system construction,and analyzes the problems that have arisen during the construction process to identify the causes of these problems.This article introduces the technical points and solutions for the construction of land information systems from multiple sources of spatial data collection and updating,spatial database construction and management,and the overall system structure.The trend of developing land information systems towards intelligence,three dimensionality,and platformization has been proposed in light of the new situation of informationization in today's society.
