Course Outline
Advanced Concepts in Drone Surveying and Photogrammetry
- Geodesy fundamentals: datums, projections, and coordinate systems.
- Accuracy levels in drone photogrammetry (absolute vs. relative).
- Integration of photogrammetry with geospatial data pipelines.
Flight Planning for High-Precision Infrastructure Mapping
- Mission design with terrain-following and oblique capture.
- Utilizing RTK/PPK drones and correction services (e.g., NTRIP).
- Controlling environmental and operational variables for optimal results.
Geodetic Control and Ground Truthing
- Deploying Ground Control Points (GCPs) and Check Points (CPs).
- Using GNSS receivers and survey-grade base stations.
- Accuracy assessment and error propagation techniques.
Processing and Modeling with Advanced Photogrammetry Tools
- Workflow optimization in Pix4D, Metashape, or equivalent software.
- Generating dense point clouds, DSMs, DTMs, and textured meshes.
- Data export and alignment with CAD and BIM systems.
Infrastructure Monitoring and Change Detection
- Digital twin creation for bridges, roads, and urban infrastructure.
- Detecting structural deformation and subsidence using drone data.
- Temporal analysis and comparison between flight missions.
Compliance, Safety, and Regulatory Considerations
