Abstract：
Suaeda salsa, phragmites australis and Spartina alterniflora are the typical salt marsh vegetation in Yellow River Delta. The Spatial-temporal Dataset of Salt Marsh Vegetation in Yellow River Delta (1999-2020) was developed based on the Google Earth Engine(GEE) together with Landsat TM/ETM/OLI, Sentinel-2 MSI optical data and Sentinel-1 SAR radar data from 1999 to 2020. Feature optimization algorithm and Random Forest algorithm were used to classify the vegetation. The dataset includes: (1) boundary data of study area; (2) spatial data of salt marsh vegetation in 13 periods from 1999 to 2020; (3) frequency data of Spartina alterniflora, Suaeda salsa and Phragmites australis from 1999 to 2020; (4) 92 sites in situ data; (5) measured spectral data. Among them, the spatial resolution of grid data is 10 m. The dataset is archived in .shp, .tif, and .xlsx data formats, and consists of 64 data files with data size of 172 MB (Compressed into one single file with 31.7 MB).Browse
