When do I need an Amazon Web Services (AWS) account to access Landsat data in the cloud? Is there a cost for that?

Landsat data continue to be freely available through traditional USGS tools such as EarthExplorer, but if you prefer to access the data in the cloud, an Amazon Web Services (AWS) account is required. 

Landsat data are available in the cloud via the AWS Oregon us-west-2 region. There is no charge for the Landsat data, but charges from the cloud vendor might apply for any storage, processing, and egress when using the direct access capability. These charges might depend on the type of account that you have. Contact Amazon with specific questions on cost.
