A Unified Framework for Fuzzy Spatio-Temporal

Recently, the interest has been focused on dynamic applications with geographic reference. These applications are commonly called as spatio-temporal applications and examine phenomena, which occur in specific geographical regions and change over time. In addition, data collected to model and analyze a phenomenon are accompanied with uncertainty. Current GIS technology turns out to be inefficient to model and handle the complex geographic phenomena, which involve space, time and uncertainty dimensions. In an effort to generate more intelligent GIS tools, this paper concentrates on representation and reasoning issues of geographic entities and introduces a framework with enhanced functionality.
