Time Series Dataset of Wuhan East Lake Changes (1990-2020) was developed based on 7 periods Landsat images of Wuhan from 1990 to 2020 (with a spatial resolution of 30 m, mainly in autumn and winter) and Google Earth images, which are integrated with the Modification of Normalized Difference Water Index (MNDWI). The dataset includes the vector boundary data, water area and shoreline length of Wuhan East Lake in every 5 years from 1990 to 2020. The dataset is archived in .shp and .kmz data formats, and consists of 42 data files in 7 groups with data size of 1.91 MB (compressed to one data file with 1.07 MB). The analysis paper based on this dataset was published in Journal of Geographical Sciences, Vol. 30, No. 4, 2020.Browse
