GIS를 활용한 지형의 개석도 분석

Abstract

In the study of geography, GIS application significantly reduces time of research comparing with the traditional manual work. It also gives possibility of effective application and connection among the research data (thematic maps, satellite images, statistic data, etc.), which allows to improve research results. Comparing with existing studies, this approach provides higher effectiveness of research results sharing and management convenience. In this study, the use of GIS in dissected degree analysis of topography allows to verify the research effectiveness and results accuracy. Traditional dissected degree analysis has been accomplished manually. This is very time and effort-consuming work, which also makes it very difficult problem to examine various space resolutions and study areas. The dissected degree analysis in using GIS in this study shows results which are considerably consistent with the results of previous researches accomplished manually. Thus, the use of GIS in dissected degree analysis of topography in particular can overpass the limits of traditional dissected degree analysis, which makes it a great alternative in terms of effectiveness.The expected results of GIS application to dissected degree analysis of topography based upon this research can be summarized as follows: ① the time of analysis is reduced significantly; ② the results of analysis for various space resolutions can be compared; ③ sharing of research results become easy.
