摘要
介绍了OpenGIS的概念,回顾了GIS软件的发展历程并分析了GIS开发中存在的问题;在综合分析组件技术用于GIS开发优势的基础上,提出了基于OpenGIS的铁路构建物三维可视化组件的设计构想;最后实现了部分组件的功能并提出GIS发展趋势。
This paper introduces the concept of OpenGIS, reviews the history of GIS software development and analyzes the existing problems at present with GIS development. On the basis of a comprehensive analysis of the advantage of COM technology, this paper brings forward the idea of designing 3-demension visual COMGIS for railway structures. The function of 3-demension visual COMGIS is partly realized and the trend of GIS development is pointed out.
