PROBLEM TO BE SOLVED: To provide a supporting system for grasping a seashore maintenance condition for supporting the grasping of the maintenance condition of the seashore.SOLUTION: When an altitude data receiving unit 10 receives altitude data measured by an altitude measuring device 106 mounted on a flying object, a gradient tints map creation unit 12 creates a gradient tints map of a sand dune and a seashore forest in the seashore of an evaluation object on the basis of the altitude data. An altitude segment map creation unit 14 creates an altitude segment map of the sand dune. A tsunami defense function evaluation unit 16 calculates an index of resistance for tsunami on the basis of the altitude and a gradient of the sand dune and a density of trees of the seashore forest. A soil amount calculation unit 18 calculates a soil amount required for realizing a predetermined reference altitude on the basis of the altitude segment map of the sand dune. When the gradient tints map is created, the altitude segment map is created and the calculation processing of the index of resistance for the tsunami and the required soil amount is performed, an aging information providing unit 20 stores the result thereof in a storage unit 22 as history information, and presents it as aging information. |
