Various relation-based systems, concerned with the representation and processing of spatial relations, have been developed in numerous application domains. In this thesis we identify the common concepts underlying qualitative spatial knowledge representation, we compare the representational properties of the different systems and we outline the computational tasks involved in relation-based spa...

There is inevitably error or uncertainty in spatial data, which are used to represent reality world, it will causes a suspicion for correctness of topological relations obtained by reasoning observation data. In this paper, we firstly describe the geometric and statistical properties of random line and area, and analyzing the effect of error in spatial data on representation of topological rela...

built environment does not “simply appear overnight, like a movie-set springing up on a vacant lot, but has to be produced”.thus, the first point in dealing with such an environment is considered to be the tracing of time in the evaluation of the city and keeping in mind that the whole is more than its parts. the last point becomes naturally understood when the process of city building is p...

A spatial object is characterized not only by its geometric extents, but also by the spatial relations existing with its surrounding objects. An important kind of spatial relations is represented by topological relations. Many models have been defined in literature for formalizing the semantics of topological relations between spatial objects in the Euclidean 2D and 3D space [6, 3, 2]. Neverthe...

Spatial relations have been investigated in various inter-related areas such as qualitative spatial reasoning (for agents moving in an environment), geographic information science, general topology, and others. Most of the results are specific constructions of spatial relations that fulfill some required properties. Results on setting up axioms that capture the desired properties of the relatio...

Spatial configurations allow for many different kinds of spatial relations between objects. Previous cross-linguistic work in this domain relies on a valuable but restricted stimulus set, the Topological Relations Picture Series (TRPS), which has two major limitations: (1) it covers a small subset of the spatial semantic domain, focusing on the IN/ON area, and (2) it covers that subset in an un...

This paper develops a series of qualitative spatial calculi that feature topological relations. While most qualitative spatial calculi have targeted spatial relations between single-type objects, our calculi support spatial relations between heterogeneous combinations of objects. Thus, with our calculi, we can disambiguate topological arrangements of objects without regard to the types of the o...

A current trend in the development of spatial-relation ontologies is to capture more and more details about the geometries of the spatial objects that are related, primarily by topological relations. In an effort to bridge between often disparate approaches, a reference system for topological relations between compound spatial objects is introduced. Its framework comprises the base relations’ c...

The visual-impedance hypothesis postulates that relational expressions which elicit visual images without a spatial component impede reasoning (Knauff and Johnson-Laird, in press). The goal of the present article is to summarize some experimental findings that support this hypothesis. Previous studies yielded four sorts of relations: (1) visuo-spatial relations, such as "abovebelow", that are e...

Spatial databases form the foundation for a Spatial Data Infrastructure (SDI). For this, a spatial database should be methodically developed to accommodate its role in SDI. It is desirable to have an approach to spatial database development that considers maintenance from the early stage of database design and in a flexible way. Moreover, there is a lack of a mechanism to capture topological re...
