Costal tidal flats are critical regions for climate change, sea level rises and human activities. Based on time-series remote sensing images and field survey data, the authors developed a supervised classification method for mapping tidal flats on the Google Earth Engine (GEE) to obtain the Tidal Flats Dataset Covers Coastal Region in North of 18°N Latitude of China (1989-2020). The dataset is yearly based during the more than 30 years and has a spatial resolution of 30 m. The dataset is consisted of 256 data files in .shp data format with the data size of 318 MB (Compressed to one single file with 201 MB).
