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.

Key words: multi-source geospatial data, identical entity matching, geometric consistency processing, semantic consistency processing, spatial-relation consistency processing
