Value-added Landsat image data of Hainan Island from 1970 to 2017

Since its establishment as Hainan Special Economic Zone, Hainan Island has achieved great development in urbanization and great changes have taken place in the natural environment. In recent years, many policies have been put forward for the construction of Hainan Island, such like Hainan International Tourism Island Construction, Maritime Silk Road and the ASEAN strategy. In this situation, the long time-sequence, high-quality satellite remote sensing data sets provide important reference to Urban Construction, Environmental Protection, Agricultural Planning, and Ecotourism. In order to learn the changes of Hainan Island, in macroscope perspective, and understand the evolution of its natural resources, since the establishment of the special economic zone, this study selected the cloudless or less cloudy Landsat series satellite remote sensing images from 1970 to 2017. Through the deep processing service system, we obtained five images which can cover the entire island of Hainan in 1970, 1988, 1998, 2008 and 2017. And the main jobs included image registration, projection conversion, band fusion and image mosaicking. With less cloud influence, this product has a large time span and can be used for scientifically analyzing the temporal and spatial changes of Hainan Island over the past 40 years, as well as in industrial application monitoring and government macro decision.
