黄河流域12.5米分辨率地形因子（坡度）数据集

数据集为黄河流域地形因子（坡度）数据，空间分辨率12.5m，数据源来自于美国国家航空航天局(NASA) 的ASF DAAC；数据通过预处理、分幅、投影、镶嵌地形指标计算四个步骤完成；坡度单位为“°”，通过严格的质量检查，通过严格的质量检查，数据完整性、逻辑一致性、位置精度、属性精度、接边精度、现势性均符合国家测绘局制定的有关技术规定和标准的要求，质量优良可靠。

This dataset contains topographic slope factor data for the Yellow River Basin, with a spatial resolution of 12.5 meters. The data source is ASF DAAC under the National Aeronautics and Space Administration (NASA) of the United States. The data was processed through four steps: preprocessing, tiling, projection, and mosaic-based topographic index calculation. The unit of slope is "°". After strict quality inspection, the data's integrity, logical consistency, positional accuracy, attribute accuracy, edge-matching accuracy and currentness all meet the relevant technical regulations and standards formulated by the National Bureau of Surveying and Mapping of China, with excellent and reliable quality.
