摘要
从空间数据的质量表达方法和管理的角度出发 ,对基于特征的空间数据不确定性管理模型进行研究。首先对现行的元数据质量管理方法进行了分析 ,指出其不足。随后根据GIS发展的趋势 ,指出空间数据质量管理面临的挑战和问题 ,进一步提出了基于特征的空间数据不确定性管理模型 。
This paper concentrates on the problem of uncertainty management of spatial data, and mainly discusses the method of feature-based quality management of spatial database. Firstly, the paper analyses the metadata method of quality management, points out its flaw. Then according to the development direction of GIS, a new method of uncertainty management, which is based on the concept of feature is proposed. The main aspects of this method are also discussed in the context.
