Advanced Drone and Photogrammetry Techniques for Infrastructure Supervision Training Course

Advanced Concepts in Drone Surveying and Photogrammetry

• Geodesy fundamentals: datums, projections, and coordinate systems
• Precision levels in drone photogrammetry (absolute vs. relative)
• Integration of photogrammetry into geospatial data pipelines

Flight Planning for High-Precision Infrastructure Mapping

• Mission design featuring terrain-following and oblique capture
• Utilising RTK/PPK drones and correction services (e.g., NTRIP)
• Managing environmental and operational variables for optimal outcomes

Geodetic Control and Ground Verification

• Deployment of Ground Control Points (GCPs) and Check Points (CPs)
• Use of GNSS receivers and survey-grade base stations
• Accuracy assessment and error propagation methodologies

Processing and Modelling with Advanced Photogrammetry Tools

• Workflow optimisation in Pix4D, Metashape, or similar platforms
• Generation of dense point clouds, DSMs, DTMs, and textured meshes
• Data export and alignment with CAD and BIM systems

Infrastructure Monitoring and Change Detection

• Creation of digital twins for bridges, roads, and urban infrastructure
• Detection of structural deformation and subsidence using drone data
• Temporal analysis and comparison across multiple flight missions

Compliance, Safety, and Regulatory Considerations

• Data privacy, geofencing, and flight permits in large-scale projects
• Ethical implications of drone-based surveillance and monitoring
• Ensuring adherence to regional and international surveying standards

Photogrammetry in Multidisciplinary Infrastructure Contexts

• Case studies in transportation, utilities, and civil engineering
• Collaborative workflows with engineering, architecture, and urban planning
• Preparation of reports and 3D outputs for stakeholders
