摘要 时空数据是一种特殊的多维数据,其每一数据项的时间戳值是单调递增的.3D R-tree把时间看作为空间的另一维,然后利用R-tree进行空间索引,查询效率比较低而且只能处理离线数据.而HR-tree将时间维孤立出来,同时保存每一时间戳的... 关键词 时空数据库;时空索引;R...
Recently, various research efforts have been conducted to develop strategies for accelerating multi-dimensional query processing using the Graphics Processing Units (GPUs). Well-known multidimensional access methods such as R-tree, B-tree and their variants, however, are hardly applicable to GPUs in ...

Real-world objects are inherently spatially and temporally referenced, and many database applications rely on databases that record the past, present, and anticipated future locations of, e.g., people or land parcels. As a result, indices that efficiently support queries on the spatio-temporal ext...
