Algorithms for Fundamental Spatial Aggregate Operations

spatial aggregates is devoted to mechanisms to support range queries, or box queries Aggregate range queries perform some aggregate operation over spatial or spatiotemporal data that fall into a user speci ed area (the range or box), possibly over some speci ed time window [17, 10, 13] Such aggregation mechanisms seem to stem from theApr 01, 2007· The Rtree is known to be one of the most popular index structures to efficiently process window queries in spatial databases Intuitively, the aggregate Rtree (aRtree) , improves the Rtree’s performance in range sum queries by storing, in each intermediate entry, preaggregated sums of the objects in the subtree Fig 1 shows an example of an aRtreeIndexing range sum queries in spatiotemporal databases

Approximate range query processing in spatial network

Jul 20, 2012· Spatial range query is one of the most common queries in spatial databases, where a user invokes a query to find all the surrounding interest objects Most studies in range search consider Euclidean distances to retrieve the result in low cost, but with poor accuracy (ie, Euclidean distance less than or equal network distance) Thus, researchers show that range search in network distanceApr 02, 2009· A probabilistic threshold range aggregate (PTRA) query retrieves summarized information about the uncertain objects satisfying a range query, with respect to a given probability threshold This paper is the first one to address this important type of queryProbabilistic Threshold Range Aggregate Query Processing
