Map evaluation device, map evaluation method, and map evaluation program

Abstract

A map evaluation device, a map evaluation method, and a map evaluation program are provided that can express the differences between a plurality of maps that should be in the same state in objective numerical values ​​and can easily extract areas that require correction on a priority basis. [Solution] When a stroke designation unit 10 designates a stroke to be compared in a first map and a second map, an outline coordinate value extraction unit 12 extracts a first outline from the first map and a second outline from the second map as the outline of the stroke, as the coordinate values ​​of the vertices defining each outline, and a matching processing unit 20 determines pairs of corresponding vertices between the first outline and the second outline based on the coordinate values ​​of the vertices defining each outline, and determines isolated vertices for which no corresponding vertex can be determined, an evaluation data generation unit 16 generates evaluation data based on the pairs of vertices and the presence or absence of isolated vertices, and an evaluation unit 18 evaluates the differences in the outlines between the first map and the second map from the evaluation data.
