[pdal] First steps using PDAL in osgeo4W

[adam steer]

Hi Silvia

Bradley will have a more precise answer about the relationship between PCL
and PDAL; PDAL’s filters.pmf (
https://pdal.io/stages/filters.pmf.html#filters-pmf) is also an
implementation of the PMF you found in PCL (Zhang et al 2003)

I usually use filters.smrf:
https://pdal.io/stages/filters.smrf.html#filters-smrf …which is is based
on: https://pdal.io/references.html#pingel2013

Parameters for ground extraction might need to change based on what the
data contain, eg houses or large sheds or forests or a mix.

It’s really worth taking the time to step through the PDAL workshop
materials, I go through them all the time to find stuff even though I’ve
taught the material before!

https://pdal.io/workshop/index.html
…and maybe this page on constructing a ground classification pipeline will
help:

Cheers
