Data sets in large applications are often too massive to fit completely inside the computers
internal memory. The resulting input/output communication (or I/O) between fast internal …

Foreword by Mark Stephen LaRow, Vice President of Products, MicroStrategy" A unique and
authoritative book that blends recent research developments with industry-level practices for …

The rise of GPS and broadband-speed wireless devices has led to tremendous excitement
about a range of applications broadly characterized as¿ location based services¿. Current …

Many location-based applications require constant monitoring of k-nearest neighbor (k-NN)
queries over moving objects within a geographic area. Existing approaches to this problem …

A variety of techniques for performing a spatial join are reviewed. Instead of just
summarizing the literature and presenting each technique in its entirety, distinct components …

Data sets in large applications are often too massive to fit completely inside the computer's
internal memory. The resulting input/output communication (or I/O) between fast internal …

This paper presents an approach for establishing vertex correspondences between two
planar shapes. Correspondences are established between the perceptual feature points …

In the big data era, rapid visualization of large-scale vector data has become a serious
challenge in Geographic Information Science (GIS). To fill the gap, we propose HiIndex, a …

Recent data stream systems such as TelegraphCQ have employed the well-known property
of duality between data and queries. In these systems, query processing methods are …

We propose a new dynamic method for multidimensional selectivity estimation for range
queries that works accurately independent of data distribution. Good estimation of selectivity …
