These jobs failed because the transcoder didn't properly handle the .tar.gz extension.

We finally got these in, but when the tiler tries to composite with them, it fails for some reason and 500s. I'll take a closer look later.
from joerd.
I just re-transcoded these and they don't break the tiler anymore, but they also aren't showing up over the top of ned13, which doesn't seem to have holes cut out for the Great Lakes.

That helps. It looks like vertical measurements are unexpected though, because there's a hillshade border around the data:

Does it need a different clip? Where could we do that?

I'm going to disable this for now. I haven't figured out a way to get rid of the stripe and the resolution isn't all that great anyway.

Re-opening for a rainy day.

Info for rainy day. These DEMs each have individual vertical offsets, I think maybe their zero height datum is the mean surface level of each lake? The offset data is available from NOAA or pre-digested in Joerd v1.

Thanks!
