摘要

PROBLEM TO BE SOLVED: To give a restriction condition in accordance with an intuitive description method, to retrieve moving locus data and to retrieve moving locus data whose shape is similar with moving locus data stored in a database as a retrieval object.;SOLUTION: For the purpose of retrieving movement restriction data being a segment having a complicated shape, information on a region to which moving locus points of moving locus data being the retrieval object belong is recorded by using a divided compartment, and an index recording information on a pass order of the divided compartment through which moving locus data passes is generated. When a retrieval condition described by retrieval language describing a geometric relation between the segment and the region is given, the divided compartment matched with the region designated by the retrieval condition is specified. Moving locus data satisfying the retrieval condition are retrieved by using the index.;COPYRIGHT: (C)2004,JPO
