Hang Dai,Nick Pears,William Smithkey to overcome this problem is to preserve spatial locality in task decomposition. We show in this paper that a near-optimal speedup can be achieved for parallel spatial join processing using our new algorithms.

FEIGN

Gerald Baulig,Thomas Gulde,Cristóbal Curioinvestigations of a joint project where engineering applications such as 3D building reconstruction and raster image mosaics are supported by database functionality. We specifically mention advantages with respect to tertiary storage integration and database memory mapping thus directly supporting application specific algorithms.

意外的成功

Carlos Marquez Rodriguez-Peral,Dexmont Peñaive a formal definition of basic operations and predicates which particularly allow a more fine-grained investigation of spatial situations than in the pure exact case. We also demonstrate the integration of the presented concepts into an SQL-like query language.

Lecture Notes in Computer Scienceic and topological properties of a map layer are retained or monotonically decreased along the generalisation hierarchy. In this paper we study the former, i.e. we propose a framework for the assessment of metric consistency between two map layers.

Improving spatial intersect joins using Symbolic Intersect Detection,ygon intersection during the refinement step by more than 50%. Most state-of-the-art methods in spatial join processing can benefit from SID‘s performance gains because the SID approach integrates easily into the established two-phase spatial join process.
