Introduction to Lidar Workflows with PDAL

Sign up or log in to save this to your schedule and see who's attending!

Feedback form is now closed.
PDAL is a widely used open source library for translating and manipulating point cloud data.  Large sponsors and users include NGA, US Army Corps of Engineers, USGS and RadiantBlue (now DigitalGlobe).  Here in the Seattle area, Azimetry and LizardTech both make use of this library.

Widely used for data format conversion, there is also very flexible workflow support including a variety of ground-point classification algorithms from academic literature, compression (laszip) and merging / tiling.  The interface is strickly command-line (no graphic editor) and involves some programmatic concepts.  However this talk is not targetted at programmers but interested users of Lidar data.

I'll overview Azimetry's experience with this library and demonstrate how it can be used to automate portions of lidar processing including initial identificatioan of outliers, course-grain classification, cropping and DEM creation.

Michael Rosen is a Senior Software Engineer with Azimetry, a medium sized Lidar production shop in Bellevue.  He is working on state-of-the-art Lidar-Production implementation efforts.  His professional interests include automated point cloud classification, multi-view photogrammetry and open source GIS software.
