Distributional data of shallow sea coral reef in Danzhou Bay Sanya Coral Reef National Nature Reserve from 1987 to 2018

Assisted by field research data, we used visual interpretation and threshold segmentation to summarize the rules of coral reef distribution,and to extract the spatial distributional data of shallow sea coral reefs in the Danzhou bay and Sanya coral reef national nature reserve.

The accuracy of the results was verified by field spectrum information collected. Finally, We obtained the spatial distribution data of shallow sea coral reefs in phase 51. This data set can be used for analysis of the temporal and spatial changes, eco-environmental changes of coral reefs, among others.
