Spatial inverse query processing
GeoInformatica, 2012Traditional 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 keyword query processing
Proceedings of the VLDB Endowment, 2013Geo-textual indices play an important role in spatial keyword querying. The existing geo-textual indices have not been compared systematically under the same experimental framework. This makes it difficult to determine which indexing technique best supports specific functionality.

Integrated query processing strategies for spatial path queries
Proceedings 13th International Conference on Data Engineering, 2002Investigates 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

Enabling Query Processing on Spatial Networks
22nd International Conference on Data Engineering (ICDE'06), 2006A system that enables real time query processing on large spatial networks is demonstrated. The system provides functionality for processing a wide range of spatial queries such as nearest neighbor searches and spatial joins on spatial networks of sufficiently large sizes.

Spatial query processing for fuzzy objects
The VLDB Journal, 2012Range and nearest neighbor queries are the most common types of spatial queries, which have been investigated extensively in the last decades due to its broad range of applications. In this paper, we study this problem in the context of fuzzy objects that have indeterministic boundaries.

Spatial query processing engine in spatially enabled database
2010 18th International Conference on Geoinformatics, 2010In 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 "

SPATIAL QUERY PROCESSING USING GENERALIZED FILTER
International Journal of Cooperative Information Systems, 2000Spatial 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.

Query Processing in Spatial-Query-by-Sketch
Journal of Visual Languages & Computing, 1997Abstract Spatial-Query-by-Sketch is the design of a query language for geographic information systems. It allows a user to formulate a spatial query by drawing the desired configuration with a pen on a touch-sensitive computer screen and translates this sketch into a symbolic representation that can be processed against a geographic database.
