Abstract:
To provide a technique for easily superimposing a cadastral map on a house display map with high accuracy.SOLUTION: An information processor creates map data. The information processor includes: a dividing section that divides a cadastral map polygon into a parcel polygon group including a plurality of parcel polygons; a generation section that generates a reference point for each of the parcel polygons; a filtering section that performs first filtering for extracting the reference point on the basis of at least one of an area and a distortion degree of the parcel polygon; and a creation section that obtains public coordinate system coordinates of the extracted reference point, using the public coordinate system coordinates of the reference point, superimposes the parcel polygon group on a house map and creates the map data.SELECTED DRAWING: Figure 1
