To facilitate development of spatial applications, we investigate the problem of modeling topological constraints in part-whole relationships between spatial objects, where the related objects may themselves be composite. An example would be countries that belong to a supranational organization, where the countries are themselves composed of states. Current topological classification schemes are restricted...
Rapid development of information technology such as mobile terminals and GPS systems enabled information services that provide location-oriented information based on users’ positions. In this paper, we propose an approach for the modeling of information integration applications that incorporate spatial information sources in addition to conventional information sources to provide appropriate location-oriented...
Topological relationships between spatial objects have been a focus of research on spatial data handling and reasoning for a long time. Especially as predicates they support the design of suitable query languages for spatial data retrieval and analysis in databases. Unfortunately, they are so far only applicable to simplified abstractions of spatial objects like single points, continuous lines, and...
