<p><P>PROBLEM TO BE SOLVED: To provide a support device for intermediate-and-mountainous-area direct payment system, capable of setting an arrow pattern having the point higher in altitude of first and second points as a starting point and the point lower in attitude as a terminal point only by determining the positions of the first and second points regardless of the altitude. <P>SOLUTION: The system includes a map information storage unit 11 which stores map information for a planar map having three-dimensional coordinate information; an acceptance unit 15 which accepts designation of the positions of the first and second points that are end points of a line segment for calculating an inclination on the map of the planar map; an altitude value acquisition unit 16 which acquires altitude values that are height-directional coordinate values of the first and second points by use of the coordinate information; a determination unit 17 which determines the heights of the first and second point by use of the acquired altitude values; an arrow pattern generation unit 18 which uses the determination result to generate an arrow pattern that is an oriented line segment having the higher point of the first and second points as the starting point and the lower point as the terminal point; and an output unit 13 which outputs the planar map and the generated arrow pattern. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
