Value-added Gaofen-1 image data of Hainan Island

As China’s second largest island, Hainan Island is a strategic node 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.作为中国第二大岛屿，海南岛是海上丝绸之路的战略节点。高质量增值卫星产品对于海南省资源与环境的动态调查具有重要意义。本研究收集了2015至2016年期间覆盖海南岛的低云量高分一号（Gaofen-1，GF-1）卫星影像。所有采集的GF-1影像均通过卫星遥感深度处理系统完成自动化处理，主要流程包括影像配准、地面控制点（Ground Control Points，GCP）采集、平差、正射校正、影像融合与影像镶嵌，最终完成海南岛增值卫星产品。该产品具备低云量、更高定位精度与色彩均衡的优势，可为海南岛的基础设施规划、生态环境保护与可持续发展提供基础数据支撑。
