지상 레이저 스캐닝 기법을 이용한 해안 지형 추출

Abstract

A laser scanning technique has been attracting much attention as a new technology to acquire location information. This technique might be applicable to a wide range of areas, most notably in geomatics, due to its high accuracy of location and automation of high-density data acquisition. In this study, the Coastal Topography was extracted using Terrestrial Laser scanning. Analysis was applied to Coastal Topography built up by two different methods : Total Station surveying and Terrestrial laser scanning technique. It was shown that about 6.54% relative error ratio. Through this Terrestrial laser scanning technique, efficient change detection of coast section can be ensured and also they can provide important information to be used when development Ocean Spatial Information System in the future.
