As previously mentioned, I presented my talk on "Filtering point clouds with PDAL and PCL" at FOSS4G North America 2016 this morning. I'm happy to announce that the slides are now posted.
If you made it out to Raleigh and saw the talk in person, thanks for attending! If not, a video of the talk should be posted in the near future. I'll be sure to share the link as soon as it is ready.
