The Impact of Geometrical Objects Generalization on the Query Execution Efficiency in Spatial Databases

Abstract

This paper presents the problem of geometrical objects generalization in relation to the geospatial queries efficiency. Authors in their research focused on a qualitative assessment of data, which are derived from the lossy generalization processes. Furthermore, they also attempted to determine the critical level of profitability of lossy generalization. There was also examined a correlation between the reduction of data details by removing vertices and a geospatial query execution speed. © Springer International Publishing Switzerland 2014.
