	abstract = {In this paper, we address the maintenance of spatial semijoin queries over continuously moving points, where points are modeled as linear functions of time. This is analogous to the maintenance of a materialized view except, as time advances, the query result may change independently of updates. As in a materialized view, we assume there is no prior knowledge of updates before they occur. We present a new approach, continuous fuzzy sets (CFS), to maintain continuous spatial semijoins efficiently. CFS is compared experimentally to a simple scaling of previous work. The result is significantly better performance of CFS compared to previous work by up to an order of magnitude in some cases.},
