Abstract
In this study, a Ridge Distinction Program was developed to improve the elevation standard, which is one of standards for mountainous districts conversion permission regulated by the Management of Mountainous Districts Act. To distinguish mountainous districts from other land types, this program assumed that the lower end of the mountainous districts is the outlet points where catchment size is 30ha. Also the program used the halfway line between the ridge and the lower end of the mountainous districts to recognize the upper slope areas. To prevent potential errors within the classification process, the areas that were classified as non-mountainous districts by the current forest type map were removed. According to the classification results by using the developed program, the 58% of the mountainous districts (
본 연구는 산지관리법의 산지전용허가기준 중 산지표고기준을 개선하기 위해 GIS를 이용하여 능선구분 프로그램을 개발하였다. 본 연구에서 개발된 능선구분 프로그램은 산지를 구분하기 위해서 집수면적이 30ha 되는 지점의 유출구를 산자락 하단부로 가정하였고, 산정부를 구분하기 위해서 5부 능선을 적용하였다. 능선구분에서의 오류를 제거하기 위해 임상도를 이용하여 산지가 아닌 지역을 제거하였다. 본 연구를 통해 개발된 프로그램의 적용성을 검토한 결과, 현행 산지관리법을 적용했을 경우 약 3%(
