The 30-m datasets of coastline changes in Hainan Island from 1990 to 2020

Dataset Overview

As the boundary between the sea and the land, information on the location and type of coastline constantly changes with environmental changes in coastal zones.The management and protection of coastal ecosystem is of strategic significance to the sustainable development of mankind. Based on Landsat TM/OLI data from 1990, 2010 and 2020, the coastline extraction algorithm based on adaptive threshold segmentation based on MNDWI was adopted in this study, and combined with field survey data, the coastline change data set of Hainan Island in 1990 -- 2020 was obtained. This data set can help Hainan Province better manage the coastal zone and Marine ecological environment and sustainable development.
