PROBLEM TO BE SOLVED: To provide a kick distance calculation device which precisely evaluates land with a street value by easily and speedily calculating the minimum value of a kick distance between arbitrary points. SOLUTION: The kick distance calculation device obtains an intersection P between a segment L1 connecting the position coordinates of a point A and a point B, and a segment L2 connecting the respective position coordinates of passing equipments Q1, Q2, Q3.... The adjacent passing equipments Q2 and Q3 along the segment L2 from the intersection P are selected and the length of a route K1 connecting the respective position coordinates of the point A, the passing equipment Q2 and the point B, and the length of a route K2 connecting the respective position coordinates of the point A, the passing equipment Q3 and the point B are calculated. Then, the kick distance of the route K1 is calculated based on the calculated value of the length of the shorter route K1 between the route K1 and the route K2. |
