I noticed the boundary file for this tile had incorrect XY coordinates (it plots in the Indian Ocean). I spot checked a laz file in the directory s3://usgs-lidar-public/UT_Ogden-FEMA_2011/ept-data/ and it seems like the incorrect coordinates are in those LAZ files as well.

From pdal info 6-9-32-37.laz --all :

Hi- do you have the full name of the bad tile? I can pass it on to folks at USGS NGTOC to see if they can fix.
Thanks,
jason

This seems to be an issue with the .ept versions of the data. I looked briefly at the laz files in:

ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/NED/LPC/projects/UT_Ogden-FEMA_2011/laz

and the XY coordinates look like they are correct UTM coordinates for the Ogden area.
