It is located in Luntai County, Bayingoleng Mongolian Autonomous Prefecture, Xinjiang Uygur Autonomous Region. The geographical location of Yangxia-Cedaya Oasis is 41°45′29″N-42°02′7″N, 84°27′15″E-85°13′42″E. The Yangxia-Cedaya Oasis consists of 17 oases with a total area of 615.42 km² (Albers) and a circumference of 484.95 km (Lambert). Among them, the largest oasis has an area of 562.45 km² and a circumference of 349.71 km. The main streams of Yangxia River and Cedaya River are 90.12 km and 44.01 km respectively. The geographical location of the mountainous part of the Yangxia-Cedaya Oasis River Basin is 42°2′25″N-42°26′39″N, 84°13′41″E-85°26′8″E. The mountainous part of the basin covers an area of 2,596.92 km² and a circumference of 334.76 km. The elevations of the mountainous part of the basin are divided into 8 categories. This dataset includes the following data of the Yangxia-Cedaya Oasis: (1) boundary data;(2) water system data that nourishes the oasis;(3) boundary data of mountainous parts of various river basins;(4) elevation classification data of mountainous parts of the basin. The dataset is stored in.kmz,.shp and.tif data formats and consists of 49 data files with a data volume of 16.9 MB (compressed into 4 files, 8.89 MB). </p>",
