Abstract：

The Weigan-Kuqa Oasis (also called Weigan-Kuche Oasis), including the Weigan River Oasis and the Baicheng-Kuqa Oasis, is located in the Aksu Administrative Region of Xinjiang Uygur Autonomous Region, China. The geo-location of Weigan River Oasis is between 40°56′57″N and 41°51′20″N, 82°07′44″ E and 83°47′25″E. The Weigan River Oasis consists of 2 oases with a total area of 6,600.17 km² (Albers projection), total perimeter of 1,239.86 km (Lambert projection). About 50.89% of the total oasis area is in Kuqa, 28.54% is in Shaya, and 20.57% is in Xinhe. The geo-location of the Baicheng-Kuqa Oasis is between 41°35′22″N and 42°15′43″N, 80°57′35″E and 82°44′37″E. The Baicheng-Kuqa Oasis consists of 52 oases with a total area of 2,034.47 km², total perimeter of 1,512.30 km. About 97.95% of the total oasis area is in Baicheng, and 2.05% is in Wensu. The main rivers which nourish and maintain the existence of the Weigan-kuqa oasis are Muzhaerte River, Kuqa River and Kamusilang River. Their main stream lengths are 230.81 km, 181.76 km and 116.18 km. The geo-location of the mountainous part of the Weigan-kuqa catchment is between 41°46′38″N and 42°38′51″N, 80°15′1″E and 83°44'40" E. The area of this part of catchment is 11,988.73 km² with about 64.35% of the total area in Baicheng, 22.87% in Kuqa and 12.78% in Wensu. The elevation of the mountainous part of Weigan-Kuqa catchment was classified into 12 types. The dataset was developed based on Google Earth images, ASTER GDEM 30 m and in situ data. The dataset is consisted of (1) boundary data of the Weigan River oasis; (2) boundary data of the Baicheng-Kuqa Oasis; (3) Weigan-Kuqa River system; (4) boundary data of the mountainous Weigan-Kuqa Catchment; (5) elevation classification data of the mountainous Weigan-Kuqa Catchment. The dataset is archived in .kmz, .shp and .tif data formats, and consists of 60 data files with data size of 72.8 MB (Compressed into 5 files with 47.5 MB).
