摘要
随着空间信息技术的飞速发展,曾经困扰国土资源管理行业应用的多源数据的集成访问,海量数据的组织管理等问题已经不再是制约的因素,但分布式、异构、多时态的空间数据如何同步更新、如何复制移植等一系列新问题逐渐衍生出来。本文旨在从技术层面,研究省市县三级的分布式、异构、多时态的土地利用现状空间数据同步复制的技术,并以省级第二次土地调查成果数据库建设为例,研究并设计了一套可行的解决方案。
With the development of the space information technology,many problems that puzzled the land resource management will not be the conditional factors,such as the compositive interview of the multi-fountain data,the management of the magnanimity data,But many new problems come forth.For example, the synchronous update and reproduce transplant of the land use space data which is distributed,fantastic structure and multi -tense.This article researches the synchronous rproduce technology of the different grade-provincial,civic or prefectural space data which is distributed,fantastic structure and multi-tense.It uses the data base constructing of the provincial secondary as an example.It works out an available project.
