Introduction: Uncertainty Issues in Spatial Information [chapter]

Robert Jeansoulin, Odile Papini, Henri Prade, Steven Schockaert
2010 Studies in Fuzziness and Soft Computing  
The discussion focuses on the diversity of spatial information, and the different challenges that may arise. Second, an overview of the contents of this edited volume is presented.  ...  The term spatial information refers to pieces of information that are associated with locations, which typically refer to points or regions in some two-or threedimensional space.  ...  But only once temporal reasoning had been sufficiently mastered, after the introduction of Allen's temporal interval relations [1] , research on spatial reasoning has blossomed [19, 45, 6, 46, 10] .  ...
