Abstract: As China’s second largest island, Hainan Island is a strategic node of of the maritime silk road. High-quality value-added satellite products are of great significance for dynamic investigations of the resources and environment of Hainan Province. This study collects Gaofen-1(GF-1) satellite images of Hainan Island with less cloud cover from 2015 to 2016. All collected GF-1 images were processed automatically by using the satellite remote sensing deep processing system. Major steps included image registration, Ground Control Points (GCP) collection, adjustment, ortho-correction, image fusion and image mosaicking, through which the value-added product for Hainan Island was completed. With less cloud, higher positioning accuracy and balanced color, this product provides basic data for infrastructure planning, ecological environmental protection and sustainable development of Hainan island.
