3D Photogrammetric monitoring services
At CREALP, we specialize in 3D photogrammetric monitoring of natural hazards and environmental processes and applied studies of remote sensing, leveraging cutting-edge aerial platforms to overcome mountainous terrain challenges across Valais. Our drones (e.g., DeltaQuad EVO) and dual-tilting camera pod for light planes (eg. Savannah, Ventura) equipped with RGB/NIR cameras and PPK positioning capture high-resolution imagery even in steep, remote high-altitude areas confined areas. By reconstructing 3D surfaces from multi-temporal datasets (comparable with LIDAR), we quantify changes in critical processes such as glacial retreat, landslides, permafrost degradation, debris flows, and flooding—providing actionable insights for hazard mitigation, empirical model validation, and policy development.
Core offerings:
- Study Site and Regional Coverage & Accessibility: Cross-valley surveys with aircraft (3–4 hour range, up to 5000m altitude) or BVLOS drones (70 km/h, 50km+ radio/LTE range), enabling rapid response to emergencies and frequent technical monitoring.
- Precision Tools: Sub-decimeter accuracy via PPK positioning and multispectral imaging for detailed geomorphological analysis.
- Interdisciplinary Database: A centralized repository of original photos, point clouds, and 3D models accessible to researchers, practitioners, and the public through our web portal map (e.g., tracking channel sediment budgets, landslides, or glacial volumes seasonally/annually).
- Affordability: Cost-effective solutions for frequent monitoring campaigns, ensuring data accessibility for environmental decision-making.
- Speed & Reliability: Partnered with multiple pilots for fast deployment, optimizing altitude (up to 4000m ASL) and mission duration (e.g., 2 hours at 3000m).
- Innovation Hub: Testbed for emerging sensors and analysis techniques, supporting advancements in geomorphology, hydrology, and remote sensing.
Key applications :
- Glaciers: Volume change, retreat tracking
- Landslides & Rockfalls: Displacement monitoring (e.g., Moosfluh)
- Permafrost: Degradation detection and assessment
- Floods & Debris Flows: Extent mapping, channel evolution
- Instabilities & Erosion: Stability analysis, sediment budgets
- Snow: snow cover and snow depth mapping
- Forests: Canopy growth
- Change Detection: Quick event response, seasonal/annual trends
