Abstract:

Based on the high spatial resolution remote sensing images of Google Earth (2 m) in 2020, the authors interpreted and developed the farmland distribution dataset in the Yaluzangbu River, Nianchu River and Lhasa River Region of the Tibetan Plateau (2020) (YLN-F2020). Then geostatistical analysis method was taken to analyze the spatial distribution pattern of farmland. The dataset includes the following data in the study area: (1) boundary data; (2) spatial vector data of farmland; (3) spatial raster data of farmland; (4) verification points data of farmland. The results show that the total area of farmland of YLN-F2020 product is 2356.15 km², and the overall accuracy is 95.2%. The farmland in this area is mainly distributed along rivers, and more farmland in the east than in the west, more in the south than in the north. The farmland was mainly distributed in the southwestern area and the eastern area. The dataset is archived in the .shp, and .tif formats, and consists of 30 data files with data size of 568 MB (Compressed into one single file with 15.5 MB).
