<p class="MsoNormal">Howard Butler will be in St. Paul in a few weeks to talk about LiDAR and his work on the PDAL, Entwine, and Greyhound projects. I thought that it would be good for people outside of the TCMUG group to get some exposure to this, so I booked
him for a “Lunch and Learn” session organized by the MnGeo Agency Collaboration group.

<p class="MsoNormal">This session is open to all, and I am hoping that many of you will come to the presentation.

<p class="MsoNormal">After your friendly data acquisition vendor drops a few terabytes of LiDAR on your desk with a thud, you might be left wondering what to do with it. The obvious things, like make a digital terrain or surface model for a little patch are
achievable in your favorite desktop monolith, but more nuanced stuff, like computing a vegetative height surface, or filtering noise from the point cloud are less obvious. Howard Butler will talk about how you can use the PDAL open source project to complete
these tasks, describe processing and data management techniques to corral an entire state's worth of LiDAR in the cloud, and describe the possibilities of getting your point clouds in the cloud with open source software. You can find out more about these softwares
at <a href="https://pdal.io"><span style="color:windowtext;text-decoration:none">https://pdal.io</span></a> and <a href="https://entwine.io"><span style="color:windowtext;text-decoration:none">https://entwine.io</span></a> <o:p></o:p></p>
