[Landsat-pds] New Landsat SNS Topic

[Sundwall, Jed]

FYI, I’ve created a new public SNS topic that anyone can subscribe to for notifications of when a new Landsat scene has been added to s3://landsat-pds. It will only accept subscriptions via SQS or Lambda. The topic publishes a message whenever a scene-level index.html file has been created, which is the last step in the process to make scene data available on S3.

Here’s the ARN: arn:aws:sns:us-west-2:274514004127:NewSceneHTML

And below what a message from it looks like with the relevant file name highlighted. This message was triggered when this index.html file was created: http://landsat-pds.s3-website-us-west-2.amazonaws.com/L8/169/060/LC81690602016015LGN00/index.html
