Landsat Commercial Cloud Data Access

Return to Landsat Data Access Overview
 

Landsat Collection 2 Level-1 data, Level-2 and Level-3 scene-based products, and Landsat U.S. Analysis Ready Data (ARD) are located in an Amazon Simple Storage Service (S3) s3://usgs-landsat requester pays bucket within the Oregon us-west-2 region.   (Note: this capability does not change existing user data access or workflows.) 
 

SpatioTemporal Asset Catalog (STAC)

All Landsat data stored in the AWS cloud platform include SpatioTemporal Asset Catalog (STAC) metadata. Key features of STAC metadata include:

• Interoperability between satellite metadata (e.g., Landsat 8 + Sentinel 2 instruments)
• Exposes data in a common, machine-readable JavaScript Object Notation (JSON) format for both end users and internal processes
• Includes direct links to Amazon Simple Storage Service (S3) objects
• Provides the ability to quickly search large collections of data using spatial and temporal areas of interest
• Lives alongside product-level metadata (Landsat Metadata (MTL), Extensible Markup Language (XML)

Simple Notification Service (SNS) Topic

The following Amazon Resource Names (ARN) are for Amazon SNS topics that provide notifications whenever a new Landsat products have been added to Landsat on AWS: Learn more about subscribing to SNS topics

Effective June 27, 2023, new SNS topics are available:

• arn:aws:sns:us-west-2:673253540267:public-c2-notify-v2 (Level-1 and Level-2 Scenes)
• arn:aws:sns:us-west-2:673253540267:public-c2-level-3-tile-notify-v2 (Level 3 Science Products)
• arn:aws:sns:us-west-2:673253540267:public-c2-ard-tile-notify-v2 (U.S. ARD Tiles)
• Each SNS topic publishes an Amazon S3 event message whenever a scene-level or product-level index.html file has been created, which is the last step in the process to make data available on Amazon S3. It will only accept subscriptions via Amazon SQS or AWS Lambda.

Documentation

The Landsat Commercial Cloud Direct Access Users Guide provides basic information on how users leverage the Landsat data in the cloud in order to enhance existing workflows by utilizing common tools available in the commercial cloud environment.

Tutorials

A number of tutorials have been established to help users better utilize Landsat data. The majority of them can be found at the USGS repository: https://code.usgs.gov/eros-user-services.
