    Modeling Checkpoint-Based Movement with the Earth Mover’s Distance

    Movement data comes in various forms, including trajectory data and checkpoint data. While trajectories give detailed information about the movement of individual entities, checkpoint data in its simplest form...

    Higher Order Vagueness in Geographical Information: Empirical Geographical Population of Type n Fuzzy Sets

    Fuzzy set theory has been suggested as a means for representing vague spatial phenomena, and is widely known for directly addressing some of the issues of vagueness such as the sorites paradox. Higher order vague...

    Capturing and Representing Conceptualization Uncertainty Interactively using Object-Fields

    We present a method for representing, recording and managing conceptualization uncertainty. We review components of uncertainty associated with semantics and metadata. We present a way of recording and visuali...

    Fuzziness and Ambiguity in Multi-Scale Analysis of Landscape Morphometry

    Recent research on the identification of landscape morphometric units has recognised that those units have a vague spatial extent which may be modelled by fuzzy sets. To date most such have looked at the lands...
