Abstract：
The coastline in the San Francisco Bay is the largest bay along the California coast of the United States, located between 121.8°W to 122.5°W and 37.4°N to 38.1°N. The dataset of the coastline types and their spatiotemporal variations in San Francisco Bay (1980-2020) 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 and muddy 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 San Francisco Bay 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 formats, and consists of 64 data files with data size of 49.4 MB (compressed to 23.0 MB in one data file).Browse
