Recently, spatial analysis in crime databases has attracted increased attention. In order to cope with the problem of discovering the closest pairs of objects within a constrained spatial region, as required in crime investigation applications, we propose a query processing algorithm called Growing Window based Constrained k-Closest Pairs (GWCCP). The algorithm incrementally extends the query window...
Spatial analysis in crime databases has recently been an active research topic. To solve the problem of finding the closest pairs of objects within a given spatial region, as required in crime geo-data applications, this paper proposes an efficient constrained k-closest pairs query processing algorithm based on growing window. It expands the window gradually instead of searching the whole workspace...
