Spatial inverse query processing

GeoInformatica, 2012
Traditional spatial queries return, for a given query object q, all database objects that satisfy a given predicate, such as epsilon range and k-nearest neighbors. This paper defines and studies inverse spatial queries, which, given a subset of database objects Q and a query predicate, return all objects which, if used as query objects with the ...

SPATIAL QUERY PROCESSING USING GENERALIZED FILTER

International Journal of Cooperative Information Systems, 2000
Spatial data, ranging from various land information data to different types of environmental data, are typically collected and used by different custodians. The full benefits of using spatial data can be achieved by combining the data from different sources covering a common region.

Integrated query processing strategies for spatial path queries

Proceedings 13th International Conference on Data Engineering, 2002
Investigates optimization strategies for processing path queries with embedded spatial constraints, such as avoiding areas with certain characteristics. To resolve complex spatial constraints during path finding, we consider two decisions: (1) the spatial relation operations (e.g. intersection) between areas and links can be pre-processed or intermixed

Spatial query processing engine in spatially enabled database

2010 18th International Conference on Geoinformatics, 2010
In spatially enabled database, spatial data and traditional structured data share same query processing engine (QPE) through the standard SQL interface. It's essential to design a robust QPE to efficiently support and process query workflow which is mixed with spatial and non-spatial predictions. Currently most of spatially enabled databases adopt the "
