Research on topological query of fuzzy spatial objects in spatio-temporal databases
Zhang Dong-jing · Information technology newsletter · 2007
Although researches on topological query of crisp regions in spatio-temporal databases are matu-ring gradually,researches on fuzzy spatial objects are not enough.Based on fuzzy theories,this paper complies with reasoning regulations on complex crisp regions,and then expounds their topological relations and predicates.This will be conducive to the development of spatio-temporal querying system.
