DeepOWT v3.25.1: Dense Sentinel-1 Time Series for Deployment and Operational Dynamics

DeepOWT (deep learning derived global offshore wind turbines) is an independent and openly accessible data set of offshore wind energy infrastructure locations and their temporal deployment dynamics on a global scale. Locations are derived by applying deep learning based object detection on ESA's spaceborne Sentinel-1 synthetic aperture radar (SAR) archive, see Global Offshore Wind Infrastructure: Deployment and Operational Dynamics from Dense Sentinel-1 Time Series Dense time series are derived by inspecting each available Sentinel-1 scene at every detected infrastructure location. One-dimensional swath profiles are generated for each acquisition and infrastructure location, showing the maximum SAR backscatter value along the horizontal axis, thereby capturing directed SAR signatures.
