댐건설에 따른 지표변화 분석을 위한 RS 기법의 적용에 관한 연구 = Application of Remote Sensing Method for analysis of surface change by dam construction

다국어 초록 (Multilingual Abstract)

It becomes base data for topographic and hydrologic analysis that evaluate surface change of basin, Various research using remote sensing recently is progressing, and it becomes indicator that analyze surface cange that evaluate land cover of surface using multi-spectral band.
Maximum Likelihood Method is used with Landsat TM image in order to analyze surface change by yongdam dam construction in this study.
There was no bi change in forest, dry field, build p area as analysis result. But, paddy area decreased from 15.07% in 1994 year to 10.73% in 2001 year that based on current water level. and, water area increased from 0.30% in 994 year to 4.01% in 2001 year that based on full water level. Also, gumgang 3 subbasin that is lowest basin showed highest water area by 23.95% of whole land cover.
