Abstract：
The coastline in the Guangdong-Hong Kong-Macao Bay Area is between 112-115°E and 21-23°N, located in the Pearl River Estuary region, which covers nine cities in the Pearl River Delta, as well as Hong Kong and Macao. The coastline types and their spatiotemporal variations in Guangdong, Hong Kong and Macao Bay Area (1979-2020) was developed based on Landsat remote sensing images of seven periods from 1979 to 2020, and Google Earth high resolution images. The coastline is defined by the mean high-water line, which is divided into two categories: natural coastline and artificial coastline. The natural coastline is divided into bedrock coastline, gravel coastline, muddy coastline and biological coastline. Artificial coastline is divided into farmland aquaculture coastline, port wharf coastline and other artificial coastline. Furthermore, the intensity of coastline length change, type structure change, and utilization degree index were calculated. The dataset includes the following data from Guangdong-Hong Kong-Macao Bay Area from 1980 to 2020: (1) spatial distribution data of coastlines and their types in seven periods (.shp, .kmz); (2) coastline type structure data (.xlsx); (3) coastline length change intensity (.xlsx); (4) coastline utilization index (.xlsx). The dataset is archived in .shp, .kmz and .xlsx data format, and consists of 64 data files with data size of 94.9 MB (compressed to 46.7 MB in one data file).
