英文摘要Fine and new digital elevation model (DEM) of riparian zone is urgently required for hydrological and environmental modeling. With the effects of water fluctuation and submersion, acquiring DEM in the riparian zone is difficult. In this study, a self-adaptive receiver operating characteristic (ROC) method was proposed to generate the DEM of riparian zone with the aid of water fluctuation (called ROC DEM). The water extent acts as an altimeter to measure the altitude with the corresponding water level. The elevation of each pixel was the optimal threshold to determine whether it was covered with water or not. With the fluctuation in water, the time-series labels of land or water and the corresponding water level of each pixel were recorded. Finally, the elevation of each pixel was obtained by acquiring the most optimal classification threshold with the ROC algorithm. The proposed method skillfully transformed the problem of acquiring the elevation of the riparian zone into a two-class classification problem. The riparian zone in the Dongting Lake (DTL) was considered as the study area to test the proposed method with the time-series Sentinel-1 synthetic aperture radar (SAR) images and the corresponding water level. The proposed method is feasible to obtain the DEM and its results are more consistent with the actual topography compared to other DEM products. The values of R-2 between the ROC DEM and GLAS and field altitude reach 0.7 and 0.9, respectively. This article presents an alternate method for acquiring the topography in the riparian zone and tidal flat.
