| 英文摘要 | We modeled the extent of inundation around Poyang Lake, China using 13 Landsat images and two digital elevation models (DEMs). Boundaries of the observed inundation extents were (a) labeled with lake-level measurements taken at a representative hydrological station and (b) interpolated to create a Water Line DEM (WL-DEM) that was used to map inundation frequency. A 30 in contour-based DEM produced slightly better results than the Shuttle Radar Topography Mission DEM, but neither DEM was accurate for Medium and low lake levels. The WL-DEM exhibited improved accuracy at medium lake levels, but had relatively high errors at low lake levels. |
