摘要
讨论GIS的基本技术体系,针对GIS应用需要提出以分布式协同计算为基本特征的新一代GIS技术。回顾GIS技术的发展历程及各代GIS技术的基本特征,分析GIS应用需求的发展趋势,提出新一代GIS应具备的基本特征;从空间数据模型、空间查询语言和空间数据分布式计算等方面讨论新一代GIS技术的理论体系,并提出现阶段可行的实现机制;介绍新一代协同计算的分布式GIS软件原型。
In this paper, the GIS basic technology system is described. According to the GIS application progress, the new generation GIS technology,which focuses on distributed and peer to peer computing,is presented. At first,this paper discusses the history of GIS technology progress and the basic technical characteristics of past generation GIS software. Based on it the trend of GIS application progress is analyzed and the basic technical characteristics of new generation GIS software are presented. From the points of spatial data model,spatial query language and spatial data distributed computing, the technical and theoretical system is discussed in detail and the feasible implement mechanisms and the new generation GIS prototype are presented.
