摘要
二三维图形界面下的交互操作是GIS应用开发中最通用的组成部分,目前尚没有一种设计模式专门解决GIS中复杂的二三维交互问题,并且,这些交互操作往往还与应用业务领域的地理语义紧密相关.这使得一些GIS开发初学者难以有效地管理GIS系统中复杂多样的交互事件.本文基于工厂模式提出了一种GIS软件设计模式——GISTool,用以将GIS应用系统开发中繁复的二三维图形交互操作抽象出来,实现GIS应用软件开发中交互事件、数据资源、结果显示的低耦合统一管理,并基于该模式开发了地下管网管理分析平台.
Abstract
2D/3D interactions in graphical interfaces are a common and complex component in GIS application develop-ment. Currently,there is no specific design pattern dedicated to addressing the complex 2D/3D interaction problems in GIS,which are often closely related to the geographical se-mantics of the application domain. This makes it difficult for some GIS developers to effectively manage the complex and diverse interaction events in GIS systems. In this article,we propose a GIS software design pattern called GISTool based on the Factory Pattern. The GISTool pattern is used to ab-stract the complex 2D/3D graphical interaction operations in GIS application systems and achieve low coupling and unified management of interaction events,data resources,and result display in GIS application software development. The under-ground pipeline management and analysis platform,is devel-oped based on this pattern.
