EARTH-FLOW DISASTER PREDICTION DEVICE, COMPUTER PROGRAM, EARTH-FLOW DISASTER PREDICTION METHOD AND MAP INFORMATION
To provide an earth-flow disaster prediction device, a computer program, an earth-flow disaster prediction method and map information, which can accurately predict earth-flow disaster .SOLUTION: An earth-flow disaster prediction device includes: a contact peak surface acquisition part which acquires a contact peak surface of an object watershed; a contact valley surface acquisition part which acquires a contact valley surface of the object watershed; a first boundary area identification part which identifies a first boundary area between an area having a difference between the acquired contact peak surface and a topographic surface of the object watershed larger than a predetermined value and an area having the difference smaller than the predetermined value; a second boundary area identification part which identifies a second boundary area between an area having a difference between a topographic surface of the object watershed and the acquired contact valley surface larger than a predetermined value and an area having the difference smaller than the predetermined value; and a danger area identification part which identifies a danger area of the object watershed on the basis of the first boundary area and the second boundary area.SELECTED DRAWING: Figure 1
【課題】土砂災害を精度よく予測することができる土砂災害予測装置、コンピュータプログラム、土砂災害予測方法及び地図情報を提供する。【解決手段】土砂災害予測装置は、対象流域の接峰面を取得する接峰面取得部と、対象流域の接谷面を取得する接谷面取得部と、取得した接峰面と対象流域の地形面との差が所定値より大きい領域と当該差が所定値よりも小さい領域との第１境界領域を特定する第１境界領域特定部と、対象流域の地形面と取得した接谷面との差が所定値より大きい領域と当該差が所定値より小さい領域との第２境界領域を特定する第２境界領域特定部と、第１境界領域及び第２境界領域に基づいて対象流域の危険領域を特定する危険領域特定部とを備える。【選択図】図１
