摘　　要：目前基于浏览器的地理信息系统通常不具备统一的图形集成能力,缺乏较强的数据表现和交互手段,系统难以扩展和重用,同时也难以满足较专业和高交互性地理信息应用,针对这一现状,提出了一种新的WebGIS前端图形集成框架。该框架提供了统一的显示控制及扩展接口,并在此图形集成框架基础上,利用富客户端技术实现了传统WebGIS前端难以实现的图形标注和空间分析等较专业的地理信息应用业务功能及相应接口,解决了WebGIS前端图形系统的扩展、交互、编辑的难题。According to the shortcomings of current WebGIS,such as lack of capacity of unified graphical integration,lack of effective means of data expression and interaction,difficult to be expanded and reused,and realize the professional and highly-interactive functions of GIS application based on web explorer,a graphical integration framework to WebGIS is introduced.The framework provides an uniform interface to display,control and expanded,realizes the professional functions and application interfaces of spatial analysis,graphic plotting,finally solves the problem of expansibility,interaction and edtion of graphic system in WebGIS.
