Definition

Spatial queries in the cloud refer to processing of spatial queries on a distributed and interconnected network of computers that provide computation, storage, and resource management capabilities elastically in large scale. Resources in the cloud can be allocated on demand, and customers only pay for what they use. Cloud offers a number of query processing infrastructure and services ranging from parallel spatial database systems to MapReduce-based systems. Common spatial queries of interest include range queries, joins, and k-nearest neighbor queries.

Historical Background

Support of high-performance queries on large volumes of spatial data becomes increasingly important in many application domains, including geo-spatial problems in numerous fields, location-based services, and emerging scientific applications that are increasingly data and compute intensive. Past research efforts fall into three major directions toward improving spatial query performance: (i) algorithmic...
