Alen Mangafić

I work at the Geodetic Institute of Slovenia in Ljubljana, contributing to various projects as a Remote Sensing/Data Analyst, GIS coordinator, and specialist. Primarily, my work revolves around the analysis of (VHR) aerial imagery, satellite imagery and LiDAR point clouds. I heavily rely on Python, GRASS GIS, QGIS, PDAL, PostgreSQL, for data torturing and distribution.

I am also a PhD candidate in the Interdisciplinary Doctoral Programme Environmental Protection at the University of Ljubljana. My research focuses on developing a synergy between hyperspectral remote sensing, machine learning, and chemical analysis for soil contamination detection and monitoring.

Point-Cloud Acrobatics: From Raw LiDAR to Stunning 3D Visuals
Alen Mangafić, Tomaž Žagar

Dive into the fascinating world of LiDAR data as we transform raw point clouds into striking 3D visualizations using a suite of open-source tools. This workshop begins by exploring the ASPRS standard, helping you understand essential concepts like point classifications, return numbers, and other fundamental attributes that define LiDAR data. You’ll learn how to correctly interpret these attributes, assess data quality, and leverage them for more insightful analysis.

Moving beyond the basics, we’ll dig into powerful open-source workflows with PDAL, GRASS GIS, WhiteboxTools for data reading, manipulation and spatial processing, and with tools like QGIS, Potree and pybabylonjs for dynamic 3D rendering. We’ll also introduce TileDB as a robust storage option to manage point-clouds as massive dataframes. Along the way, we’ll tackle real-world tasks like gridding, interpolation, vectorization, and classification, highlighting effective approaches to manage and visualize large-scale point clouds in a reproducible manner.

By integrating Python scripts with these specialized tools, you’ll discover how to automate complex processing chains and generate stunning outputs that bring your LiDAR data to life. While basic Python knowledge is helpful, it’s not mandatory — anyone eager to learn new techniques can follow along. By the end of this hands-on workshop, you’ll not only grasp the core concepts behind LiDAR data but also have the practical skills to handle and present it in exciting, visually compelling ways.
