Mapping results of photovoltaic solar panels in Hainan Island before and after Typhoon Yagi in 2024

'pre_typhoon.tif' is the extraction result of photovoltaic solar panels on Hainan Island before Typhoon Yagi. 'post_typhoon.tif' is the extraction result of photovoltaic solar panels on Hainan Island after Typhoon Yagi. The resolution is 20 meters. Note on Analysis: The "post_typhoon. tif" file is the direct output of the PUL-RF classifier (with a classification accuracy of approximately 82%, as shown in the accuracy evaluation in the article). In order to ensure the robustness and fidelity of the statistical analysis presented in subsequent studies, a classification refinement step was applied to this output. This process involves manual visual interpretation to correct obvious omissions caused by cloud cover and image loss after the typhoon, in order to ensure that the application analysis in 3.3 reflects the actual situation as closely as possible.
