The Weihe River is the biggest branch of the Yellow River of China. The Weihe River basin covers partly the area of Shanxi, Gansu provinces and Ningxia Hui autonomous region. The boundary of the basin is from the Mt. Niaoshu (2,609 m) in the west, and goes to the southeast to the Mt. Maji (1,658 m) and Mt. Taibai (main peak of Qinling, 3,767 m), and then goes to the east to Mt. Zhongnan (2,604 m), Mt. Huashan (2,160 m), and to meet the Yellow River near the Tongguan town[1–2]. From the Mt. Niashu (2,609 m) to the northeast, it goes through the Longzhong Plateau, then Mt. Huajialing (2,450 m), Mt. Liupan (2,928 m), to Mt. Baiyushan (1,823 m), and then follows the Mt. Huanglong to meet the Yellow River[2–3]. The geolocation of the basin is from 103°58′18″E in the west to 110°16′28″E in the east, and from 33°41′47″N in the south to 37°24′30″N in the north. The total area of the basin is 134,731.12 km2, and the boundary line is 2,768.24 km[4]. The most historical heritages, such as the Xi’an city, one of the oldest capitals of China, are located in the basin[5].
Weihe River basin belongs to Shaanxi province, Gansu province and Ningxia Hui Autonomous region (Table 1)[6]. Regarding the area, about half of the Weihe River basin (49.88%) belongs to Shaanxi province; followed by Gansu province (approximately 44.03%), and then Ningxia Hui autonomous region (6.09%).
The boundary data of the Weihe River basin was developed based on the ASTER-DEM[7] with the statistic models and validated by the Google Earth images. The data is archived in both .kmz and .shp[8] formats with the compressed data size of 8.47 MB.
