Drone Surveying: Accurate Data from the Air

Drone surveying with TEDAMOS DroneCam enables the efficient capture of construction sites and infrastructure assets from the air. The resulting imagery is processed into accurate 3D models and georeferenced orthophotos.

All data is automatically transmitted, processed and made available through the TEDAMOS Web Portal. This provides a reliable basis for planning, quality control and project documentation.

Autonomous and Automated Drone Surveying

Fully automated drone systems independently handle the entire flight process – from take-off and mission execution to landing. Regularly updated aerial imagery is captured without any on-site personnel and made available for digital project documentation.

Applications

  • Infrastructure and linear construction projects
  • Large-scale construction sites (building and civil engineering)
  • Natural hazard monitoring

Use Cases

  • Construction documentation and progress tracking
  • Volume and earthworks calculations
  • Cross-section and longitudinal profile analysis
  • As-built verification and quality control

Manual Drone Surveying

For flexible, project-specific applications, drone flights are carried out on demand and tailored to project requirements – particularly during construction phases where a higher level of detail and situational flexibility is required. Alternatively, imagery can also be captured using the client's own drone systems.

Applications

  • Civil engineering works (excavation, utilities and pavement construction)
  • Detailed surveys of complex construction areas
  • Targeted inspections when short-notice information is required

Use Cases

  • Construction phase and condition documentation
  • Detailed analysis and evidence documentation
  • As-planned vs. as-built comparisons and inspection surveys
  • Installation verification and construction quality control

Large-Scale and Infrastructure Surveying with Wingtra Drones

The Wingtra drone provides highly efficient coverage of large areas. Thanks to its long flight time, high cruising speed and integrated GNSS technology, extensive sites and linear infrastructure can be surveyed quickly and accurately.

Applications

  • Large-scale sites and project areas
  • Linear infrastructure (roads, railways and utility corridors)
  • Topographic surveys in open terrain

Use Cases

  • Surveying and asset inventories
  • Orthophotos and digital terrain models (DTM/DSM)
  • Volume and earthworks calculations
  • Planning and project base data

Visualisation Options in TEDAMOS Web

Orthophotos

Georeferenced, distortion-free aerial imagery provides a precise basis for surveying, planning and analysing terrain and infrastructure assets.

Volume Calculations

High-resolution imagery enables precise volume calculations of earthworks, stockpiles and excavation materials. By comparing current surveys with previous datasets or defined reference surfaces, volume changes can be tracked accurately over time – ideal for construction projects, demolition works, stockpile management and landfill operations.

3D Models

Detailed 3D terrain models and infrastructure visualisations provide an intuitive and efficient basis for analysis, planning and project communication.

As-Planned vs. As-Built Comparisons

CAD plans can be overlaid with drone survey data, making it possible to identify deviations between design and construction at an early stage – for example, when verifying the position of electrical conduits or installation points before concrete placement.

Deformation Analysis

Drone survey data enables the detection and quantification of terrain and surface changes, such as those caused by excavation works, embankment construction or heavy rainfall. TEDAMOS automatically calculates and visualises both deformations and volume changes.

Construction Progress Documentation

Regular drone surveys provide consistent aerial imagery, creating a complete visual record of construction progress and project development over time.

How Our Clients Benefit from Drone Surveying

“The automatically processed and clearly presented drone survey data greatly supported us in verifying the elevation levels of the railway track foundation. This allowed us to approve follow-up works promptly on a section-by-section basis – a decisive factor during the tightly scheduled five-month line closure.”
