Earlier this week we created a KML file to allow you to preview the latest Sentinel imagery. We used the fact that Sentinel imagery is available via Amazon Web Services (AWS). Given that Landsat 8 imagery is also available on AWS we thought it would make sense to do the same for Landsat 8 imagery.
Simply download this KML file, and click on any tile and it will show you the six most recent Landsat 8 images for that tile.
Clicking on the link below the image takes you to the relevant AWS download page. On the AWS download page, click the thumbnail to see a much larger thumbnail.
