【摘要】 本文主要研究地理信息系统数据质量控制和数据格式转换的意义、内容、方法。目前,虽然一些GIS软件提供了对空间数据、属性数据、空间拓扑关系等进行数据检查和数据处理的功能,减少了由于人机交互干预产生的数据质量问题,但是就数据质量控制而言是远远不够的,因此,进行数据质量控制是十分必要的。地理数据是GIS应用的关键和核心。由于GIS软件平台非常多,GIS数据结构复杂,数据模型不同且在不断发展,解决多格式数据交换一直是近年来GIS应用系统开发中需要解决的重要问题。本文以地球空间数据交换格式为基础,主要对以下几个方面的内容进行研究和探索: 1.分析研究地理信息系统中的数据质量控制的内容和方法。 2.分析地球空间数据交换格式,研究矢量数据交换格式与shape文件数据格式转换的可能性 3.尝试性的利用面向对象的思想,创建数据质量控制控件和编制数据转换程序,并进行初步实现。 文章最后对研究的结果进行总结,并对未来的发展作了展望更多还原

【Abstract】 This paper mainly researches the meanings, contents and methods of data quality control and data format transformation, Now, some GIS software are provided for the functions of data check and data processing on 3D data, attribute data, spatial topology relationship, and so on, which greatly decrease the problems of data quality from human-machine interactive interfere, As for data quality control, these methods are not enough, Thus, it is important to make data quality control, The geographical data is the key and the core of GIS application . Due to many GIS software platforms, Complicated data structures, different and continuous developing models in GIS, Realizing the transformation among some kinds of data is always an important problem in the development of GIS application in recent years. In this article, based on the study of Geo-spatial data transformation format, the following contents are studied:1: Analyzed contents and methods of data quality control in GIS 2: Studied the compatibility between the vector data transformation format and shape file data format.3: This paper tried to establish data quality control and workout data transformation procedure by making use of oriented-object idea and process accidence realizes.At last, the result of the researching and studying is summarized and the future development tendency is looked forward to in this article.更多还原
