This way of describing the relationship of A to B is known as the \4-intersection model", and is studie=-=d in [EF91]-=-. The 4-intersection model is relatively coarse. Finer distinctions between relationships of regions can be obtained by counting the number of connected components in the intersection of A with B, and... |

Another way of describing the relationship of A to B, which provides forsner distinctions than in Galton's technique, is a renement of the 4-intersection model also by Egenhofer and Franzosa [=-=EF95]-=-. Some recent work in this area includes the investigation of relations between three dimensional regions [Zla99]. Since it is possible to regard time as the third dimension, this is likely to provide... |

However, models of time with two dimensions (event time and database time) are of p... |

This uses a lattice of levels of detail in a similar way to Stell and Worboys stratied map spaces [SW98]... |

This threefold classification has been used by Worboys (1998b) as the basis of a theory of finite resolution spatial data, and underlies all applications of rough set theory in the spatial context (=-=Beaubouef & Petry, 2001-=-; Bittner & Stell, 2001). The system of three extents is not the only one, and Bittner and Stell (1998) and Bittner (1997) have shown how it can be made more detailed by taking account of how the regi... |
