TL;DR: The paper is a overview of the major qualitative spatial representation and reasoning techniques including ontological aspects, topology, distance, orientation and shape, and qualitative spatial reasoning including reasoning about spatial change.
Abstract: The paper is a overview of the major qualitative spatial representation and reasoning techniques. We survey the main aspects of the representation of qualitative knowledge including ontological aspects, topology, distance, orientation and shape. We also consider qualitative spatial reasoning including reasoning about spatial change. Finally there is a discussion of theoretical results and a glimpse of future work. The paper is a revised and condensed version of [33,34].

TL;DR: The types of transitions possible for the RCC-8 topological relations under each distinct notion of spatio-temporal continuity are investigated and a hierarchy of conceptual neighbourhood diagrams is provided.
Abstract: We explore different intuitive notions of spatio-temporal continuity and give a formal characterization of continuity for space-time histories.We investigate the types of transitions possible for the RCC-8 topological relations under each distinct notion of spatio-temporal continuity and provide a hierarchy of conceptual neighbourhood diagrams.

TL;DR: A general formal framework for continuity and continuous transitions in mereotopology for spatio-temporal histories is presented and the correctness of the conceptual neighbourhood for the qualitative spatial representation language RCC-8 is sketched.
Abstract: Continuity from a qualitative perspective is different from both the philosophical and mathematical view of continuity. We explore different intuitive notions of spatio-temporal continuity. We present a general formal framework for continuity and continuous transitions in mereotopology for spatio-temporal histories and thus sketch the correctness of the conceptual neighbourhood for the qualitative spatial representation language RCC-8.
