一种动态实时的遥感专题应用系统定制框架

A dynamic and real-time customization framework of remote sensing thematic system

遥感专题应用系统广泛用于遥感影像的加载、分析、专题提取、出图等.为实现遥感专题应用系统动态、实时和可扩展的定制化开发,设计了一套基于组件的遥感专题应用系统定制框架:定义了组件划分方式,将专题系统划分为功能类组件和容器类组件,建立了组件属性和组件间的关系;采用XML文件描述遥感专题应用系统中的组件,并提供从XML到遥感专题应用系统的解析方法;设计了遥感专题应用系统定制平台,提出一种动态实时的软件设计方法,可以"所见即所得"地定制遥感专题应用系统,并将其保存为XML文件.采用该定制平台定制的多个专题系统已应用于相关部门.该框架为快速高效定制遥感专题应用系统提供了一种新的开发设计模式,降低了遥感数据在多行业应用的技术门槛,减少重复性开发工作.

Remote sensing thematic system is used for image loading,analyzing,thematic extracting,drawing,and it is widely used in various industries.In order to develop a customizable remote sensing thematic system with dynamic,real-time and extensible module configuration,a component-based design framework of remote sensing thematic system was proposed.Following the framework,the thematic system was divided into functional components and container components,with the properties of the components and the relations between the components prespecified.An XML document was then used to describe the system and could be parsed to the thematic system.At last,a software design platform was developed.Some thematic systems customized by this platform have been applied in relevant departments.This framework provides a new design mode for software development which makes it convenience for using remote sensing data in multiple industries and reduces repetitive development of software.
