%X This dataset is generated based on the ALOS 12.5m DEM data cropping, covering the topographic elevation information of the typical watersheds of Chaohu Lake Basin, Chu River Basin, Lishiahe River Area and Yangtze River Delta Demonstration Area. Through the acquisition and analysis of high-precision topographic data, the topographic relief and terrain characteristics of the study area are comprehensively reflected, and the spatial resolution of the data can meet the needs of refined topographic research. After analysis, this dataset provides scientific basis and decision-making support for water resources allocation and disaster prevention and mitigation strategies in the basin, as well as important data support for the construction of the flood simulation model and the study of regional sustainable development.
