This node export a cloud-masked, median composite image from a specified image collection. The image is exported based on a defined region of interest (ROI) and date range, and saved as a GeoTIFF file. This node allows for the customization of bands, cloud percentage threshold, and export resolution.
Input Data:
Region of Interest (ROI): A geometric object defining the area of interest for the image collection.
GEE Collection (collection): A variable specifying the image collection to be used (e.g., 'COPERNICUS/S2').
Save Folder (save_folder): A variable specifying the folder path where the exported GeoTIFF file will be saved.
Start Date (start_date): A variable specifying the start date for the image collection filter.
End Date (end_date): A variable specifying the end date for the image collection filter.
Cloud Percentage (cloud_percentage): A variable specifying the maximum allowed cloud cover percentage for images in the collection.
Band List (band_list): A ariable specifying the bands to include in the exported image, as a comma-separated string.
Resolution Scale (r_scale): A variable specifying the resolution scale for the export.
File Name (file_name): A variable specifying the name of the exported GeoTIFF file.
Output Data:
GeoTIFF File: A GeoTIFF file saved to the specified folder, containing the median composite image of the specified bands, clipped to the ROI.
