environmentaltools.download.download_single_sentinel2_image(image_info: dict[str, Any], image_index: int, total_images: int, collection: ee.ImageCollection, study_area: ee.Geometry, output_directory: Path, scale: int = 10) → bool[source]

Download a single Sentinel-2 image with vegetation indices.

Extracts an image from a collection, clips it to the study area, and downloads it using geemap. Skips download if file already exists.

Parameters:

  • image_info (dict) – Image metadata from Earth Engine containing properties like ‘system:index’ and ‘system:time_start’.

  • image_index (int) – Current image index (for progress tracking).

  • total_images (int) – Total number of images to process.

  • collection (ee.ImageCollection) – Pre-created collection containing the image.

  • study_area (ee.Geometry) – Study area geometry for clipping.

  • output_directory (Path) – Directory where files will be saved.

  • scale (int, optional) – Spatial resolution in meters. Defaults to 10.

Returns:

True if download successful or file exists, False otherwise.

Return type:

bool

Example

>>> info = {'properties': {'system:index': 'T30STG_20200601', ...}}
>>> success = download_single_sentinel2_image(
...     info, 0, 10, collection, area, Path("./output")
... )
