China Offshore Wind Turbine SAR Dataset (COWT-SAR)

The COWT‑SAR dataset provides a vectorized inventory of offshore wind turbines (OWTs) across China’s coastal waters for the period 2020–2025. Derived from Sentinel‑1 SAR imagery using the structure‑aware deep learning framework SA‑OWTDet, the dataset includes 8,593 turbines with attributes such as geographic location, installation year, distance to shore, water depth, and associated sea area. This dataset supports the consistent identification, mapping, and monitoring of offshore wind energy infrastructure, and facilitates applications in energy system analysis, marine spatial planning, infrastructure management, and a wide range of geospatial studies.COWT-SAR数据集提供了2020至2025年时段中国近海水域离岸风力发电机组（offshore wind turbines，OWTs）的矢量化清单。本数据集基于哨兵-1合成孔径雷达（Sentinel-1 SAR）影像，采用结构感知深度学习框架SA-OWTDet构建，共包含8593台机组，其属性涵盖地理位置、投运年份、离岸距离、水深及所属海域等信息。 该数据集可实现离岸风电基础设施的标准化识别、制图与监测，并可支撑能源系统分析、海洋空间规划、基础设施管理及各类地理空间研究等多类应用场景。
