A dataset of mangrove vector along the coast of Guangdong Province during 2015–2020

<p indent="0mm">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 figure out the distribution and utilization of mangroves along the coast of Guangdong province. We selected in the dataset 119 Gaofen-2 (GF-2) satellite remote sensing images of Guangdong province with less cloud cover from 2015 to 2020. In the following of the preprocessing of the collected GF-2 images, we adopted the object-based image analysis (OBIA) to extract vector data of mangroves. The accuracy assessment demonstrates that the overall classification accuracy, Kappa coefficient and production accuracy of the dataset are 95.83%, 0.8872 and 85.83%, respectively. This dataset presents the distribution and area changes of mangroves along the coast of Guangdong Province during 2015–2020. It 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.
