黄河流域DEM

2000年黄河流域涉及九个省、自治区：青海、四川、甘肃、宁夏、内蒙古、陕西、山西、河南、山东，90M网格数字高程模型。项目来源：国家重点基础研究项目“中国主要水蚀区土壤侵蚀过程与调控研究”，用于提取地形因子和流域边界，用于水文建模等。服务对象为从事地学、水文、水土流失研究的学生和科研人员。数据收集时间为2000年，数据采集地点湖北省，东经96°~119°；北纬32°~42°，投影方式：Krasovsky_1940，Albers。The 2000 90-meter grid Digital Elevation Model (DEM) covers the Yellow River Basin, which spans nine provinces and autonomous regions: Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan, and Shandong. This dataset originates from the National Key Basic Research Program titled "Soil Erosion Processes and Regulation Research in Major Water Erosion Areas of China". It is developed to extract topographic factors and basin boundaries, and is applicable for hydrological modeling and other related research purposes. The target users include students and researchers engaged in geoscience, hydrology and soil and water loss research. Specific data information is as follows: Data collection time: 2000; Data collection location: Hubei Province; Geographic coordinate range: 96°E~119°E, 32°N~42°N; Projection method: Krasovsky_1940, Albers.
