Abstract: Guangdong province is one of the regions with the largest mangroves area, the widest range and the most abundant species in China. It is very significant to find out the location and situation of mangroves along the coast of Guangdong province. The dataset collects 119 Gaofen-2(GF-2) satellite remote sensing images of Guangdong province with less cloud cover from 2015 to 2020. After all of the collected GF-2 images were preprocessed, object-based image analysis (OBIA) is adopted to extract vector data of mangroves. Accuracy assessment demonstrates that the overall classification accuracy, Kappa coefficient and production accuracy of the data set are higher than 96%, 0.88 and 82%, respectively. This product presents the status and area changes of mangroves in Guangdong province coast during 2015–2020, which can be used as the basic data for the protection, restoration and management of mangrove resources, as well as wetland dynamic monitoring and marine environment change in the region.
