Spatial information service retrieval is one of the main problems that need to be solved in the application of space information. In this paper, we systematically analyzed the research status of spatial information service retrieval. We introduced the concept scope of spatial information service retrieval and object form in retrieval, and made the classification for the existing methods. Based on the analysis of the principle and application of typical methods, we summarized the characteristics of each category and pointed out the problems in future research.
