摘要
提出了空间数据质量模型,分析了质量检验与评价工作流程,论述了"空间数据质量控制与评价系统"的总体设计思想、程序实现流程、软件总体结构及功能,并简要介绍系统的关键技术。
Spatial data quality model is advanced at first in this article.Then spatial data quality testing and evaluating work procedure is analysized.On the basis of the former discussion,general design idea,programme implementation procedure,general soft ware structure and function of Spatial Data Quality Control and Evaluating System are dissertated in detail.Key techniques of the system are also simply introduced.Lastly,future reseach direction is discussed.
