The management of spatial data in geographic database systems gained increasing importance during the last decade. Due to the high complexity of objects and queries and also due to extremely large data volumes, geographic database systems impose stringent

Distributed Spatial Skyline Query Processing in Wireless Sensor Networks
free download

Abstract. Spatial skyline queries can be used in wireless sensor networks for collaborative positioning of multiple objects. However, designing a distributed spatial skyline algorithm in resource constrained wireless environments introduces several research challenges: how

An efficient window retrieval algorithm for spatial query processing
free download

Abstract An algorithm is presented to answer window queries in a quadtree-based spatial database environment by retrieving the covering blocks in the underlying spatial database. It works by decomposing the window operation into sub-operations over smaller window

GPU-based spatial indexing and query processing using R-Trees
free download

ABSTRACT R-trees are popular spatial indexing techniques that have been widely used in many geospatial applications. The increasingly available Graphics Processing Units (GPUs) for general computing have attracted considerable research interests in applying the

Distributed Spatial Query Processing over MPI
free download

Abstract. Communication between multiple database nodes in Distributed Spatial Database Systems (DSDB) must be as efficient as possible. This requires a message passing paradigm fit to achieve this. In this way, we have tried to apply MPI standards to implement

Data Parallel Quadtree Indexing and Spatial Query Processing of Complex Polygon Data on GPUs.
free download

ABSTRACT Fast growing computing power on commodity parallel hardware makes it both an opportunity and a challenge to use modern hardware for large-scale data management. While GPU (Graphics Processing Unit) computing is conceptually an excellent match for

Cost Models and Efficient Query Processing over Existentially Uncertain Spatial Data
free download

Abstract:The domain of existentially uncertain spatial data refers to objects that are modelled using an existential probability accompanying spatial data values. An interesting and challenging query type over existentially uncertain data is the search of the Nearest

Algorithms for Processing of Spatial Queries using R-trees. The Closest Pairs Queryand its Application on Spatial Databases
free download

Abstract This thesis addresses the problem of finding the K closest pairs between two spatial datasets (the so-called, K Closest Pairs Query, K-CPQ), where each set is stored in an index structure belonging in the R-tree family. There are two different techniques for solving this

Two-layer Linguistic Spatial Query Processing
free download

ABSTRACT In this paper, we adopt the two-layer linguistic spatial query processing system to increase the retrieval flexibility of image data. A flexible system framework for linguistic spatial object queries is proposed for retrieving ambiguous and not-accurately processed

Shortest Path Algorithm for Spatial Query Processing in Road Network
free download

Abstract: If any algorithm has n-shortest path then it has some problem like path similarity among the network expansion and determined path describing turn prohibition. GPS system is an application in the road network field. the meaning of path similarity that is alternative

An Active Word Partitioning Iterate Algorithm for Spatial Query Processing

Abstract The application of standard qurry processing are shown to emerge from the nature

SURVEY ON CONFIDENTIALITY OF THE USER AND QUERY PROCESSING ONSPATIAL NETWORK
free download

Abstract The administration of transhipment systems has become increasingly important in many applications such as position-based services, supply cycle management, travel control, and so on. These applications usually involve queries over spatial networks with

GPU-based Batched Spatial Query Processing on R-Trees
free download

ABSTRACT R-trees are popular spatial indexing techniques that have been widely used in many geospatial applications. The increasingly available Graphics Processing Units (GPUs) resources for general computing have attracted considerable research interests in

Spatial Approximate String Keyword content Query processing
free download

ABSTRACT: Web users and content are increasingly being geo-positioned, and increased focus is being given to serving local content in response to web queries. This development calls for spatial keyword queries that take into account both the locations and textual

Advanced query processing on spatial networks
free download

Recent advances in GPS and mobile communication technologies have allowed applications to emerge that can access and exploit location information about (moving) objects on road networks. Location-based services enable car drivers to search for

Narrative for Paper Query Processing Using Distance Oracles for Spatial Networks
free download

The computation of distance along a network is critical for most of the spatial operations. However, it is not easy to do that in an efficient way. You can choose to store the n2 distances between all pairs, which are not a good option because of the large space

Abstract Smart mobile devices and advanced wireless networks make the vision of pervasive computing come into reality through context aware services. A wireless spatial data broadcasting is a natural way of pervasive information services by providing

Query Processing by Mining Spatial Database
free download

Abstract: Spatial database is a database which encompasses the spatial data like zonal data, data about population and education. In this paper, we address the issue of creating spatial tables which are mined by spatial queries and produce the statistical output. Four

Efficient query processing for spatial and temporal databases
free download

Spatial and temporal database systems have developed dramatically over the past two decades. Many applications in multimedia, bioinformatics, geographical information systems, and neuroinformatics require the storage and access of spatial and temporal

Processing kNN Query on Spatial Polygons Using DSB-tree
