GIS基础地理数据质量检查及其监控体系构建

GIS Fundamental Geographical Data Quality Examination and Software Monitoring

随着GIS应用的日益广泛,其基础地理数据质量问题越来越得到重视。本文对GIS基础地理数据的质量从检查内容、误差源、检查方法方面进行了研究,最后以数字线化图为例对软件监控方法的主要内容进行了探讨。

With the applications of GIS growing up,attentions are increasingly given to the quality of Fundamental Geographical Data.This research on the quality of Fundamental Geographical Data is conducted from the scope of examination,the error sources and the methods of examination.Then the Digital Line Graph are taken for example to discuss the main methods of software monitoring.
