SPACE DATA ANALYSIS APPARATUS, SPACE DATA ANALYSIS METHOD, AND SPACE DATA ANALYSIS PROGRAM

摘要

PPROBLEM TO BE SOLVED: To discover attribute information and a combination of attribute information satisfying a density condition surely with a small amount of data operation. PSOLUTION: Processing for selecting records which have the identical attribute information from among a group of records including position information to show a position in space equal to two-dimensional or larger and a plural pieces of attribute information belonging to different attributes is performed every attribute information. On the basis of the position information of the selected record, when the selected record meets the prescribed density condition, the attribute information used for the record selection is stored and the stored attribute information is combined with one another among different attributes to generate a combination of the attribute information. A record having the combination of the attribute information is selected from among the group of records. On the basis of position information of the selected record, when the selected record meets the prescribed density condition, the combination of the attribute information used for the selection is stored.
