This paper presents a new framework for modeling topological relations among objects of type point, line, and region. The main contributions are in two directions: First, the formalism proposed allows specifying all possible relations by means of symmetric matrices (whereas the usual formulation of such relations does not have this property). Symmetric matrices enable the efficient and automatic verification of valid matrices associated only with the possible topological relations. Second, it allows the specification of cases where two objects are spatially related in more than one way (e.g., a line that crosses a given region in one part and is adjacent to the same region region in another part). This increases the flexibility that users a...
