Study on Fuzzy Spatial Location Model and Spatial Query
نویسندگان
چکیده
The spatial relationships plays an important role in GIS spatial data modeling, spatial query and spatial analysis etc. From the cognitive view, we represent and apply the information of relationships between spatial objects in the real world in computer system, study the fuzzy extension about description of spatial relationships at the base. Guided the spatial query the paper makes the model on the base of regular indefinite spatial inferring, puts fuzzy theory and spatial relationships theory into the spatial query practice. The paper found indefinite spatial inferring model based on the regular rules and embed it in space decision support system as the fuzzy spatial inference machine. It involves various spatial problems such as topology, orientation, base direction, naming distance, comparison distance, scale, shape and so on. Every aspect has made some progress, solves the fuzzy location and query problems in applying GIS and get better result in the experimental test. Keyword: spatial query, fuzzy inference, fuzzy location, inference machine, GIS.
