Python LiDAR & Point Cloud Workflows
Design and chain PDAL pipelines, classify ground returns, generate DTMs and DSMs, and automate batch processing — backed by reproducible code patterns, standards-compliant data handling, and production-grade QC.
Two focused tracks: PDAL Pipelines for execution architecture, and Point Cloud Standards for the binary, classification, and CRS fundamentals every workflow depends on.
What you'll find here
Two tracks of practical, code-first material aimed at production teams working with airborne, terrestrial, and mobile LiDAR.
PDAL Pipelines
PDAL pipeline architecture, stage chaining, memory and parallel execution, attribute mapping, filtering, reprojection, and validation.
Point Cloud Standards
LAS/LAZ structure, ASPRS classification, coordinate reference systems, point density metrics, and metadata/header integrity.
