[pdal] Setting all points to a single class?

[Andrew Bell]

It's hard to know without seeing output.

What do you get when you run:

pdal info --filters.stats.enumerate=Classification
--filters.stats.dimensions=Classification

on the result (P001_E1_clip_class.las)
?

Also, you can set the value of all points with the syntax:
"Classification[:]=101" for the "assignment" option.  In your case, you're
excluding points with the value 0 and greater than 255, which may not be
what you want.
