Fuzzy Spatial Querying with Inexact Inference
نویسندگان
چکیده
The issue of spatial database accuracy has been viewed as critical to the successful implementation and long-term viability of the geographic information system (GIS) technology. In order to improve the spatial querying accuracy and quality, the problems associated with the areas of fuzziness and uncertainty are of great common in the spatial databases. In this paper, we are dedicated to develop an approach that can perform fuzzy spatial querying under uncertainty. An inferring strategy under uncertainty is investigated. The study shows that the fuzzy set and the certainty factor can work together to deal with spatial querying. Querying examples implemented by FuzzyClips are also provided.

An inexact inferencing strategy for spatial objects with determined and indeterminate boundaries
.For many years, spatial querying has been of interest for the researchers in the CIS community. Any successful implementation and long-term viability of the CIS technology depends on the issue of accuracy of spatial queries. In order to improve the accuracy and quality of spatial querying, the Toblems associated with the areas of fuzziness and uncertainty need to be addressed There has been a ...
متن کاملConstructing and matching fuzzy graphs of volumetric primitives hypotheses
In practical image querying applications, complex graphs often have to be compared to verify the similarity between two models. Since there is always uncertainty while models are constructed, the nodes and the edges require fuzzy attributes to properly describe the scene or the object. This paper addresses the problem of matching graphs with fuzzy attributes (GFAs) obtained by hypothesizing vol...
متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملFuzzy Sets Approach to Spatial Analysis and Planning - a Nontechnical Evaluation
Uncertainty in spatial analysis and planning has conventionally been treated as a consequence of random occurrence of exact spatial events. The present paper, however, argues that fuzziness is actually a major contributory factor to most of the uncertain spatial behavior. Exactitude in representing, analyzing, and predicting human behaviors over space and time is difficult if not impossible to ...
