【摘要】 电子地图是现在高新技术的产物,是随着计算机软、硬件的发展而产生和发展的。它的产生不仅在社会诸多的领域得到了广泛的应用,而且在这些领域取得了巨大的成功。随着电子地图的广泛应用,如何提高电子地图的制作开发的效率成为当前的热门话题。组件式软件技术已经成为当今软件技术的潮流之一,基于组件开发是软件开发的一次革命。GIS组件推出,不仅具有许多传统GIS工具无法比拟的优点,而且为传统GIS面临的多种问题提供了全新的解决思路,也为各种电子地图应用系统的设计制作等方面革新和完善提供了契机。本文阐述了组件技术的演变、原理和组件技术的技术特点以及其发展前景。介绍了GIS组件特点并对GIS组件MapX和二次开发进行了详细的阐述。文章最后以组件MapX的应用研究为背景,结合面向对象的可视化编程工具,对应用MapX组件开发电子地图的视图设计、属性数据的管理等问题进行了重点研究,完成了系统的空间数据采集、管理、处理、分析、存储等功能。更多还原

【Abstract】 Electronic Map is one of products of hi-tech industry. With the development of software and hardware industry,it comes into being and makes progress gradually.Widely using makes it become a heat topic of how to mke electronic map efficiently.As well known, Component Object Model is one of the most popular standards for the component technology which makes up for the defects and drawbacks of the traditional methods. Component technology is adopted and employed in the construction of information system. Component technology is the latest development of the object-oriented technique. Bearing such qualities of being open, flexible manageable and effective, etc. with this new technique applied to the construction of information system, the reusability of the software and the development efficiency of the system can be raised. In this paper, firstly, through the discussion of COM structure and Active control technology, the principal and implemental way of COM technology are introduced. Secondly, this paper summer the characteristics of MapX that is GIS ActiveX components developed by MapInfo Company. Finally, based on the discussion of fundamental and implemention of MapX component, an electrical map system is designed and made. Researching indicates that general function requirements of electronic map are satisfied with using this ActiveX.更多还原
