Course Outline
Advanced Concepts in Drone Surveying and Photogrammetry
- Geodesy fundamentals: understanding datums, projections, and coordinate systems.
- Evaluating accuracy levels in drone photogrammetry (absolute vs. relative).
- Seamless integration of photogrammetry into geospatial data pipelines.
Flight Planning for High-Precision Infrastructure Mapping
- Mission design incorporating terrain-following and oblique capture techniques.
- Utilising RTK/PPK drones and real-time correction services (e.g., NTRIP).
- Managing environmental and operational variables to ensure optimal outcomes.
Geodetic Control and Ground Truthing
- Strategic deployment of Ground Control Points (GCPs) and Check Points (CPs).
- Operating GNSS receivers and survey-grade base stations effectively.
- Conducting accuracy assessments and applying error propagation techniques.
Processing and Modelling with Advanced Photogrammetry Tools
- Optimising workflows in software such as Pix4D, Metashape, or equivalent platforms.
- Generating dense point clouds, Digital Surface Models (DSMs), Digital Terrain Models (DTMs), and textured meshes.
- Exporting data and aligning it with CAD and BIM systems.
Infrastructure Monitoring and Change Detection
- Creating digital twins for bridges, roads, and broader urban infrastructure.
- Identifying structural deformation and subsidence through drone data analysis.
- Performing temporal analysis and comparing outcomes across different flight missions.
Compliance, Safety, and Regulatory Considerations
- Navigating data privacy, geofencing, and flight permit requirements for large-scale projects.
- Addressing the ethical implications of drone-based surveillance and monitoring.
- Ensuring full compliance with regional and international surveying standards.
Photogrammetry in Multidisciplinary Infrastructure Contexts
- Reviewing case studies across transportation, utilities, and civil works.
- Fostering collaborative workflows with engineering, architecture, and urban planning teams.
- Preparing comprehensive reports and 3D outputs for stakeholder review.
