PROBLEM TO BE SOLVED: To provide an attribute information integration device of map data, the attribute information integration method of the map data, and the attribute information integration program of the map data for integrating the attribute information of the map data at low costs and with high precision.;SOLUTION: A second numerical value proportional distribution section 26 reads first map data from a first map data storage part 28, and reads second map data from a second map data storage part 30, and proportionally divides the numerical values of a second item based on the area rate of the second type of region overlapped with the first type of region. A first numerical value proportional distribution part 24 totals the proportionally divided numerical values of the second item for every first type of region, and proportionally divides the numerical values of the first item for every second type of region based on the rate of the proportionally divided numerical values of each second item to the total value. A first numerical value totaling part 32 totals the numerical values of the first item proportionally divided by the first numerical value proportionally division part 24 for every second type of region, and reflects it as the numerical values of the first item for every second type of region.;COPYRIGHT: (C)2010,JPO&INPIT
