Range aggregate processing in spatial databases
A range aggregate query returns summarized information about the points falling in a hyper-rectangle (e.g., the total number of these points instead of their concrete ids). This stone studies spatial indexes that solve such queries efficiently and proposes the aggregate Point-tree (aP-tree), which achieves logarithmic cost to the data set cardinality ( independently of the query size) for two ...

Approximately processing aggregate range queries …
Processing aggregate range queries on remote spatial databases suffers from accessing huge and/or large number of databases that operate autonomously and simple and/or restrictive web API interfaces. To overcome these difficulties, this stone applies a revised version of regular polygon-based search algorithm (RPSA) to approximately search aggregate range query results over remote spatial ...

A Scalable Algorithm for Maximizing Range Sum in Spatial ...
We first review the range aggregate processing methods in spatial databases. The range aggregate (RA) query was proposed for the scenario where users are interested in sum-marized information about objects in a given range rather than individual objects. Thus, a RA query returns an ag-gregation value over objects qualified for a given range. In

01-08-2019 · Abstract. Based on Spark platform, we propose an efficient top-k spatial join query processing algorithm on big spatial data, in which, the whole data space is divided into same-sized cells by using a grid partitioning method.Then spatial objects in two data sets are projected and replicated to these cells by projection and replication operations respectively, meanwhile a filtering operation ...
