数値地形を用いた改良山成り計算の一方法

抄録

According to the terrain conditions of the projected areas, various methodss for farm land design are nowadays adopted.
Most of these methods depend on the hand-operated calculation. In actual stage of the design, troublesome and enormous volumes of calculations are repeatedly required. Furthermore, the best relevant results extracted from these calculations are not assured in theory.
Considering the above difficulties, an automatic calculation method by using computer was developed regarding to“Kairyo Yamanari Ko”which needs the most complicated calculations. This method uses digital topographic maps. Determining plan height of each farm land automatically, this method satisfy the reasonable and effective operations.
