Location-based services (LBS) constitute an emerging application domain involving spatio-temporal databases. In this paper, i) we propose a classification of LBS, depending on whether the user (query object) and the data objects are moving or not and ii) we provide algorithms for the efficient support of real applications, for every class. We also survey recent work in query processing for the proposed LBS algorithms and sketch open issues for future research.
