%X Path search and spatial query are considered as two independent topics in database research.The processing of path query with spatial constraint needs both path computation and spatial query.To provide path computation with spatial constraint,two processing strategies are considered:(1) whether pre-processing spatial operation before path computation,and (2) whether pre-filtering spatial objects before path computation.Based on these two strategies,four integrated spatial path query processing approaches are proposed in this paper.
