<div>Hi Scott, you’re correct that we currently have a mix of Pre-Collection and Collection 1 data in the bucket. Our goal is to have the entire Landsat mission and the latest collection in S3. Work is underway to that end but unfortunately depends on timelines
that we don’t own so I don’t feel comfortable providing anything there. Feel free to reach out to me if you have any further questions. </div>

<div class="">I’ve noticed that Landsat on AWS is mostly “Pre-collection”. But coming from the USGS archive (e.g. Earth Explorer), I was expecting to find the same Collection-1 archive on AWS. Will the AWS archive be brought into sync with the USGS archive?
Over what timeframe?</div>

<div class=""><br class="">
</div>
<div class="">As an example, for path 047 row 027 there is Collection-1 data that goes back to 2013, but the Collection-1 data on AWS is just to 03/2017 (<a href="https://landsatonaws.com/L8/047/027/" class="">https://landsatonaws.com/L8/047/027/</a>)</div>
<div class=""><br class="">
</div>
<div class="">Scenes after 03/2017 match the Collection-1 scheme:</div>

<div class=""><a href="https://landsat-pds.s3.amazonaws.com/c1/L8/047/027/LC08_L1TP_047027_20170502_20170515_01_T1/index.html" class="">https://landsat-pds.s3.amazonaws.com/c1/L8/047/027/LC08_L1TP_047027_20170502_20170515_01_T1/index.html</a><span class="Apple-tab-span" style="white-space: pre;">
</span></div>
<div class=""><br class="">
</div>
<div class="">But all earlier scenes are pre-collection</div>
