La’ang Co,lake area,remote sensing,1972-2023


Using the Landsat series and GF1 remote sensing images as data sources, the authors developed vector boundary data of La’ang Co from 1972-2023 through manual visual interpretation, and calculated the corresponding lake area to obtain the La’ang Co changes dataset (1972-2023). The dataset includes the vector boundary and area of La’ang Co in 27 periods from 1972, 1977, 1994, 2000-2023. In which, the area changes during the half of century is 21.63 km² the largest area is 269.95 km² in 1977, the smallest is 248.32 km² in 2023. The spatial resolution of the dataset is 30 m. The dataset is archived in .shp data format, and consists of 189 data files with data size of 729 KB (compressed into 1 file with 498 KB).
