Dimension-Refined Topological Predicates Mark McKenney, Alejandro Pauly, Reasey Praing, and Markus Schneider   View Paper (PDF)   Return to Session 7: Data Modeling - Performance Evaluation Abstract Topological predicates, as derived from the 9-intersection model, have been widely recognized in GIS, spatial database systems, and many other geo-related disciplines. They are based on the evaluation of nine Boolean predicates checking the intersections of the boundary, interior, and exterior of a spatial object with the respective parts of another spatial object for inequality to the empty set. In this paper, we replace each Boolean predicate, which is a topological invariant, by another topol ... ©2006 Association for Computing Machinery
