Abstract

In this demonstration, we present a visualization system offering two advanced solutions that can efficiently address a novel multi-criteria optimal location query by using Overlapping Voronoi Diagrams (OVDs). Our system not only displays an example that applies the advanced solutions to a practical optimal location query, but also visualizes the process of query evaluation by using the solutions, which can help users better understand the two solutions in a more intuitive way. The Real Region as Boundary (RRB) approach calculates real regions of overlapped Voronoi cells, while the Minimum Bounding Rectangle as Boundary (MBRB) approach approximates the cells by their MBRs to simplify region overlapping calculation. For efficient query evaluation and better demonstration, global and local datasets are managed separately and only the local dataset is displayed in a limited visualization area. User interactions are provided in diverse manners in our system by using the Standard Widget Toolkit (SWT) and Open Graphics Library (OpenGL).
