论文首先引入GIS以及需求分析等概念,同时简要阐述需求分析与GIS项目之间的关系以及需求分析在GIS项目中的重要性.并结合现今世界GIS发展形式对GIS的应用前景进行讨论.详细讲述需求分析以及分析需求的步骤和需求分析的流程,并重点讨论需求分析的法则,目的为了结合实践更好的将需求分析运用到项目中去.需求分析,是一个项目提出方和承担方相互沟通的过程,一方是系统的使用者,一方是系统的制造者,在系统制造过程中,只有双方相互配合,共同对系统进行设计才能最后达到使用的要求.以GIS在地震防震救灾中的应用为例,系统的研究需求分问题,进一步阐明GIS工程需求分析研究的重要性和发展的迫切性.
The paper first introduces concepts and so on GIS as well as demand analysis,simultaneously is brief elaborates between the demand analysis and the GIS project relations as well as the demand analysis in the GIS project importance.And unifies the nowadays world GIS development form to carry on the discussion to the GIS application prospect.Detailed narration demand analysis as well as analysis demand step and demand analysis flow,and key discussion demand analysis principle,goal in order to unify practices well utilizes the demand analysis in the project.The demand analysis,is a project proposed Fang He undertakes the process which the side communicates mutually,a side is the system user,a side is the system manufacturer,in system manufacture process,only then both sides coordinate mutually,together carries on the design to the system to be able finally to achieve the use the request.Take GIS in the earthquake quakeproof disaster relief application as the example,a system research demand minute question,further expounds the GIS project demand analysis research importance and the development urgency.
