%X This data includes lake and river elements of five Central Asian countries. Using Albers' equal area conic projection, using ENVI and ecognition software, the authors selected the green band and near-infrared band which strongly reflected the water body to carry on the superposition calculation, superposed the TM data under the generated vector layer, and extracted the lake and River elements through manual intervention correction To generate the distribution data of lakes and rivers in Xinjiang and Central Asia. See this data document for data attribute information. The data can be used as scientific data to investigate the distribution of lakes and rivers in Central Asia. This data is vector data, and the data attribute information includes the following fields: polygon feature idarea: area perimeter: objectid: Lake River number.
