The data is the reservoir distribution dataset of the north slope of Tianshan River Basin, which is comprehensively prepared by using topographic map and remote sensing image. The scale is 250000, and the projection is latitude and longitude. The data includes spatial data and attribute data, and the attribute field is Name (reservoir name), reflecting the reservoir distribution status of River Basin in the northern foot of Tianshan Mountain around 2000.
National Basic Geographic Information Center
China's administrative regions are basically divided into three levels: provinces (autonomous regions, municipalities directly under the central government), counties (autonomous counties, cities), townships (nationality townships, towns). In order to meet the needs of user statistics and cartography, we have published 1:1 million national administrative division data sets according to the national basic geographic information center. The administrative division data of Heihe River Basin were prepared. This data reflects the current situation of administrative divisions in Heihe River basin around 2008, including the information of provincial, regional and county-level administrative divisions. Its main attributes (such as area, code of administrative divisions, province (autonomous region), city (region, autonomous prefecture)) come from China's administrative divisions published in 2008.

This dataset is TM remote sensing data covers western China, around the 1980s. Data attributes: Pixel Size: 30-meter reflective: Bands 1-5 and 7 60-meter thermal: Band 6 Output Format: GeoTIFF Resampling method: cubic convolution (CC) Map Projection: UTM – WGS 84 Polar Stereographic for the continent of Antarctica. Image Orientation: Map (North Up) The data was partially downloaded from the USGS http://eros.usgs.gov/ website, and partly collected from various projects. The data folder is named the row and column number where the image is located. The folder contains TM 7 bands images (* .tif), header files (* .met, * .hdr) and thumbnails (jpg). The naming format of image files is row and column number _TM image mark (5t), and image acquisition time _ band number.
