This is the dataset generated and related code for a research on High-Quality Cloud-Free Optical Image Generation Using Multi-Temporal SAR and Contaminated Optical Data The dataset generation process is as follows: Download Data from Google Earth Engine (GEE): The data download is managed by two scripts in the folder: chapter5\data_download. The main script calls a secondary script to execute the download process. Configuration: To run the download, you must adjust the study area and time period parameters within the main function. Temporal Configuration: For the two-phase dataset, imagery from July was used. For the three-phase dataset, imagery from August was added as a supplement. Generate the Final Dataset: Once the data is downloaded, processing scripts in chapter5\data_generation are used to generate the final dataset. The dataset contains two sub-datasets: two temporal version and three temporal version.
