In this paper, we introduce the concept of a moving objects data warehouse (MODW) for storing and querying multidimensional spatio-temporal data.  ...  First, we apply a tiling strategy that determines the zone belonging to the nine cardinal directions of each spatial object at a particular time and then intersects them.  ...  By applying our tiling strategy, an objects interaction graticule can be generated for any two region objects A and B.  ...

Particularly, RSATree enables arbitrary queries and flexible binning strategies by leveraging three schemes, namely, an R-tree-based space partitioning scheme to catch the data distribution, a locality-sensitive  ...  However, the queries are limited to the predefined binning schema of preprocessed data cubes.  ...  ACKNOWLEDGMENTS We wish to thank all the anonymous reviewers for their valuable comments, and all the participants for their active participation.  ...

More generally, an increasing variety of sensors is generating massive amounts of data whose quantized nature frequently leads to rasterized data structures.  ...  Examples include 1-D time series, 2-D imagery, 3-D image time series and x/y/z spatial cubes, and 4-D x/y/z/t spatio-temporal cubes.  ...  Steven Keens, with whom the author co-chairs the WCS.SWG, and Arliss Whiteside have contributed substantial suggestions for improvement during their proofreading of the WCPS draft.  ...

The performance experiments reported in this thesis were carried out with an implementation of UB-trees as a middleware layer on top of SQL.  ...  Last but not least I thank the Deutsche Bahn (German Rail), since the solution to many algorithmic problems (like the range query algorithm, multidimensional hierarchical clustering) and many new ideas  ...  In Section 8.2 we will illustrate the applicability of our technique to OLAP scenarios by using a multidimensional index to cluster the data cube of a data warehouse in order to efficiently process OLAP  ...

The size of this comparison differentiates our study as well with 19 systems compared, four benchmarked to an extent and depth clearly exceeding previous papers in the field; for example, subsetting tests  ...  data, and SPARQL and CIPHER on graph data.  ...  In the "area of interest tiling" strategy, hot spots are indicated and the system automatically determines an optimal partitioning.  ...
