the Landsat-pds includes good scenes for all locations. If we don’t include this list, then many areas including US and Europe will have limited value since they will all just be snow and heavy cloud. I would actually put this is a priority over converting
the existing scenes.<o:p></o:p></span></p>

of older scenes converted. I have a list of the ‘best’ 5 prior to 2015/1/1. Will look to have someone here review the system you set up. Not clear to me what EC2 instances you are using for the current scripts.</span><o:p></o:p></p>

<p class="MsoNormal">The scripts are currently running on a "worker" system operated by Planet Labs on Amazon. The exact way I run the scripts is a bit ideosyncratric to to us. The only thing that isn't in the public repo at the low level is a script that
reads all the tarq files and fires off a separate l8_process_scene.py job for each. The l8_process_run.py (and l8_process_scene.py) I use are the normal versions. <o:p></o:p></p>
