aws landsat LandsatOliTirs

rslearn.data_sources.aws_landsat.LandsatOliTirs¶

This data source is for Landsat 8/9 OLI-TIRS imagery on AWS. It uses the usgs-landsat S3 bucket maintained by USGS. It includes Tier 1/2 scenes but not Real-Time scenes. See https://aws.amazon.com/marketplace/pp/prodview-ivr4jeq6flk7u for details about the bucket.

This data source supports direct materialization: if the "ingest" flag is set false, then ingestion will be skipped and windows will be directly populated from windowed reads of the underlying cloud-optimized GeoTIFFs on S3.

Progress while scanning metadata is logged at DEBUG level; set RSLEARN_LOGLEVEL=DEBUG to enable debug logging.
