【摘要】 开发地理信息系统是一个复杂的过程,涉及非常复杂的方面:数据获得,验证,空间关系和拓扑关系表示等。如何高效地,科学地开发一个具有良好软件特性的GIS是开发者关心的问题。然而,在GIS软件设计过程中,常常需要整体开发思想指导,需要应用有效方法去实现GIS软件的复用性,规范性,可交互性,可共享等特性。 但是,我们目前缺乏相对完整的,系统的,有针对性的开发思想指导GIS开发,缺乏有效方法来实现这些特性。只是按照常规的软件开发的流程进行,没有充分体现GIS在软件开发,设计,管理等方面的特点。 基于上述问题和相关学者研究成果,我们按照软件工程开发流程,对GIS软件开发进行了较为深入跟踪和研究,并在此基础上初步整理和阐述了一个整体的开发思想,通过使用UML进行规范化地描述,同时具体分析了一个多分辨率的数据模型。我们初步对GIS软件开发的研究,对于提高软件开发的效率,便于软件设计的交流,及其数据共享和系统集成有一定的意义。

【Abstract】 The development of Geographic Information System is a complicated process including very complex aspects: the data acquirement and validation, the expression of spatial relation and topological relation etc. It is a concerned question how to design and develop a stable, interactive, reuseable GIS effectively .But there is often short of effective ways and means to realize these traits wholly.The research of content,process and mean about GIS is lacking. According to flow of routine software development at present, it can’t show the traits of development , designing , management in GIS. The development in GIS should make use of software engineering idea and achievement of research . It is necessary to show cognition about GIS wholly and utilize CASE tools to improve development efficiency.Based on the questions and some research of scholars ,we track and research thoroughly in GIS according to software engineering idea. We synthesize a whole development idea primarily and express it by UML, meanwhile analyze a multi-resolution data model in detail. It is meaningful for improving software development efficiency, communication of software development, data shared and system integration.
