Continuous change in spatial regions,fferent changes may be continuous with respect to different selections from this set of measures. We apply these different forms of continuity in a discussion of various cases which can be regarded as idealisations of processes of change that are of interest in geography and other spatial sciences.

Fiat and bona fide Boundaries: Towards an ontology of spatially extended objects, to have application above all for our understanding of issues involving contact, division, and separation, issues which have posed serious difficulties for the ontological theories of boundaries that have been proposed hitherto.

Identification of fuzzy objects from field observation data, Four object models are proposed to represent objects of different uncertainty levels. The proposed methodology is illustrated by a case study in coastal geomorphology of Ameland, The Netherlands. The methodology developed in this paper will also be applicable for modeling natural environments and physical processes in other fields.

Complex regions in topological queries,nnected regions with or without holes are allowed. Incorrect answers to topological queries involving complex regions are therefore avoided. Our work nicely extends the Egenhofer-Franzosa‘s model, originally developed for modeling binary topological relationships between simple regions.
