On 20 April 2022, Amna Qayyum successfully defended her PhD entitled "A qualitative representation of moving point configurations with illustrations in micro traffic analysis". She obtained the degree of Doctor of Sciences: Geomatics and Surveying (UGent). Supervisors were professors Nico Van de Weghe (Department of Geography, Ghent University) and Bernard De Baets (Department of Data Analysis and Mathematical Modelling, Ghent University). In her work, Amna presents a new qualitative spatiotemporal approach (PDP) to represent motion data. The work consists of a comprehensive study of the practical applications, implementation and technical aspects of the PDP representation.
