摘要: 国产MapGIS软件是国内应用范围较广的地理信息系统之一,不仅绘图功能强大,而且向用户提供了二次开发库.笔者简要介绍了物探图件表现形式和图例制作要求;针对航空物探项目中的图件绘制特点,利用MapGIS组件,以C#语言为平台提出了一个解决方案,可快速实现大批量图件裁剪、图例制作以及图面配置等工作,有效地减少了人为误差的引入,大大地提高了工作效率.文中对程序设计中的关键点和涉及MapGIS组件开发的主要代码进行了较详尽地阐述.

Abstract: As one of geographic information systems,MapGIS software has been widely applied in geological field in China,which not only has powerful function in map drawing but also provides the secondary development library for users.The forms of expression in geological map and the requirements of legend producing are introduced briefly in this paper.On the basis of components of MapGIS software and according to the map's features of airborne geophysics survey,the authors present the new solutions using C Sharp programming language for rapid maps clipping,legends producing and design and some other work.As a result,the artificial errors are reduced effectively and then the drawing efficiency is raised by multi-times.The key techniques and the codes about components of MapGIS are described in detail. -
