%X This data set includes L1 data products of Landsat ETM in Weihe River Basin and L1 and L2 data products of Landsat 8. The data are from the National Aeronautics and space website of the United States（http://ladsweb.nascom.nasa.gov/data/search.html ）， The spatial resolution of the data product is 30m, the cloud amount is less than 20%, and the spatial range is 103 ° 58 ′ 17 ″ - 110 ° 16 ′ 28 ″; 33°41′46″—37°24′30″。 The time range of Landsat ETM data products is from January 1, 2009 to December 31, 2012; The time range of L1 and L2 data of landsat8 is from January 1, 2013 to December 31, 2020.  L1 data product is only the data that has been geometrically corrected without radiometric calibration and atmospheric correction; L2 data products have been processed with radiometric calibration, atmospheric correction and geometric correction.
