Convex Hull-Based Metric Refinements for Topological Spatial Relations
نویسنده
چکیده
Metric refinements of qualitative topological relations not only provide more details of distinctions between spatial entities, but also theoretical interests and applications. This paper developed an alternative way of metric refinements for improving the identification of the eight topological relations with the aid of the extension of convex hull concept to defining relations between two spatial regions. We defined some area terms and relative ratio factors for metric refinements that can be successfully and uniquely applied to the eight basic relations.

Splitting Ratios: Metric Details of Topological Line-Line Relations
Within the geographic domain, an important class of problems relies on geometric abstractions in the form of lines where, for instance, transportation networks and trajectories of movements are typically perceived or modeled at such a generalized geometric level. To support querying and computational comparisons, oftentimes multi-resolution models are needed to guide users from coarser to finer...

Nowadays, geospatial information systems (GIS) are widely used to solve different spatial problems based on various types of fundamental data: spatial, temporal, attribute and topological relations. Topological relations are the most important part of GIS which distinguish it from the other kinds of information technologies. One of the important mechanisms for representing topological relations...
متن کاملMetric details of topological line-line relations
Many real and artificial entities in geographic space, such as transportation networks and trajectories of movement, are typically modeled as lines in geographic information systems. In a similar fashion, people also perceive such objects as lines and communicate about them accordingly as evidence from research on sketching habits suggests. To facilitate new modalities like sketching that rely ...

Spatial relations are the basis for many selections users perform when they query geographic information systems (GISs). Although such query languages use natural-language-like terms, the formal definitions of those spatial relations rarely reflect the same meaning people would apply when they communicate among each other. To bridge the gap between computational models for spatial relations and...
متن کاملVague Topological Predicates for Crisp Regions through Metric Refinements
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 data retrieval and analysis in spatial databases and geographical information systems. Whereas research on this topic has always been dominated by qualitative methods and by an emp...
