Abstract	Floodplain is a flat plain between levees and rivers. This paper suggests a methodology for analyzing the land uses in the Nakdong River floodplain using the RapidEye imagery and the given LiDAR(LIght Detection And Ranging) DEM(Digital Elevation Models). First, the levee boundaries are generated using the LiDAR DEM, and the area of the floodplain is extracted from the given RapidEye imagery. The land 2014년 10월 12일 접수 Received on October 12, 2014 / 2014년 12월 19일 수정 Revised on December 19, 2014 / 2014년 12월 23일 심사완료 Accepted on December 23, 2014 1 (주) 지오씨엔아이 공간정보기술연구소 Institute of Spatial Information Technology Research, GEO C&I Co., Ltd. ※ Corresponding Author E-mail : choung12osu@gmail.com Analysis of Land Uses in the Nakdong River Floodplain Using RapidEye Imagery and LiDAR DEM 190 FIGURE 1. Profile of a river basin, modified from figures in Lee(2010) and KWRA(2009) uses in the floodplain are identified in the extracted RapidEye imagery by the ISODATA(Iterative Self-Organizing Data Analysis Technique Analysis) clustering. The overall accuracy of the identified land uses by the ISODATA clustering is 91%. Analysis of the identified land uses in the floodplain is implemented by counting the number of the pixels constituting the land cover clusters. The results of this research shows that the area of the river occupies 46%, the area of the bare soil occupies 36%, the area of the marsh occupies 11%, and the area of the grass occupies 7% in the identified floodplain.
