Training on LiDAR for Advanced Spatial Analysis: Data Processing and 3D Modeling

This course provides participants with advanced skills in processing, analyzing, and visualizing LiDAR (Light Detection and Ranging) data for complex spatial applications. Participants will gain hands-on experience handling raw point clouds, performing preprocessing, filtering, and extracting critical features for mapping, modeling, and analysis. The training emphasizes practical workflows from LiDAR data acquisition to 3D modeling, enabling informed decision-making in urban planning, infrastructure development, forestry, disaster management, and environmental monitoring.

The program covers key techniques for 3D spatial modeling, terrain and surface analysis, feature classification, and integration with GIS platforms. Participants will learn to use industry-standard software such as LAStools, PDAL, QGIS, ArcGIS Pro, CloudCompare, Python, and Google Earth Engine to manage large LiDAR datasets efficiently and generate accurate, high-resolution 3D representations of physical environments. Real-world examples illustrate how LiDAR enhances geospatial analysis, improves infrastructure planning, and supports environmental and resource management.

Additionally, participants will explore applications of LiDAR in urban modeling, forestry inventory, hazard mapping, mining, and environmental monitoring. By the end of the 10-day course, attendees will be able to implement LiDAR workflows, create detailed 3D models, integrate LiDAR data with GIS and remote sensing datasets, and communicate geospatial insights effectively for diverse sectoral applications.
