In RETURN-project/makeDataCube: Prepare raster datasets for upscaling recovery indicators

Description

Download Landsat scenes. Several criteria can be set to select scenes of interest: the extent of the study area, the time period of interest, the preferred sensors, tiers and maximum cloud percentage. Only scenes are downloaded that are not in the queue file yet. After download to a temporary folder, these scenes are compressed to a .tar.gz file, added to the the queue file and the level1 folder. Finally, the original downloaded files are removed from the temporary folder.
