I'm having trouble reading several LAZ files from the USGS for the
MN 2020+ collects. Is there a way I can tell if the LAZ files are
bad or if there is a PDAL bug? Apparently the LAZ files in question
can be opened and viewed in GlobalMapper. My test is simply running
'pdal info' on the file. I have tested with PDAL 2.3.0, 2.5.3, and
2.5.4, all built from source. <br>
<br>
These files fail with: <br>
<br>
"PDAL: readers.las: Extra byte specification exceeds point length
beyond base format length."<br>

And these files fail with either:<br>

or<br>
