Abstract

The spatial information recently observed by various sensors and platforms has been provided by national portals through the establishment of a database over a number of time periods, with easy access to various types of information. Therefore, it is possible to analyze the changes in the national territory space according to time. This study is intend to analyze forest changes based on a case of some areas in Heongseong and Wonju using the various spatial information observed in many ways, such as aerial photographs, ortho photos, digital topographical maps, DEM and DSM. DSM created by the airborne lidar and the aerial photos was able to analyze forest change areas more effectively than DEM of topographical maps. Also, forest management and analysis could provide basic data for efficient preservation and management of forests using spatial information.

최근 다양한 센서 및 플랫폼에 의해 관측된 공간정보는 여러 시기에 걸쳐 데이터베이스를 구축하여 국가 포털에서 제공하고 있으며 다양한 공간정보에 대한 접근이 용이하다. 따라서 시간의 변화에 따른 국토 공간의 변화에 대한 분석이 가능하다. 본 연구에서는 다시기에 관측된 다양한 공간정보들인 항공사진, 정사영상, 수치지형도, DEM 및 DSM 등의 자료들을 활용하여 횡성과 원주 일부지역의 사례를 중심으로 산림 변화를 분석하였다. 항공라이다와 항공사진을 이용하여 생성된 DSM이 수치지형도의 DEM보다 산림변화지역을 효과적으로 분석할 수 있었다. 또한 공간정보를 활용하여 산림 관리 및 분석을 수행함으로써 산림에 대한 효과적인 보전 및 관리를 위한 기초 자료를 제공할 수 있었다.
