| 摘 要： | 多源地理空间数据的处理和应用近年来受到广泛关注,多源地理空间数据一致性处理技术是消除多源、异构、多时相、多尺度地理空间数据之间矛盾和问题的关键技术,也是地理空间数据生产和更新的主要手段。本文讨论了多源地理空间数据不一致性产生的原因,从几何、语义、关系3个方面对一致性处理技术的研究进展进行分析和阐述,在此基础上分析地理空间数据一致性处理目前仍存在的问题,对未来的研究重点做出展望。

| Abstract: | The processing and application of multi-source geospatial data have been widely concerned recently. The consistency processing of multi-source geospatial data is a significant technology to eliminate the problems amang multi-source, heterogeneous, muti-temporal and multi-scale geospatial data, as well as a major way to produce and update geospatial data. In this paper, the main causes of inconsistency in multi-source geospatial data are firstly discussed, then the research progress of consistency processing is overviewed and evaluated from 3 aspects, namely geometric, semantic and spatial-relation. Based on the analysis above, a series of tough problems to be solved are expounded, where the future research priorities are put forward sequentially. |
