Scan Data
Scan data refers to digital information captured from the physical world using measurement technologies such as laser scanning, LiDAR, or photogrammetry. This data typically comprises point clouds, meshes, or high-resolution imagery, and forms the foundational input for creating 3D models, BIM environments, and digital twins.
Scan data represents real-world geometry with a high degree of accuracy and spatial resolution. It is collected via devices such as terrestrial laser scanners, drones, mobile mapping systems, or handheld scanners. The resulting datasets may include:
- Raw point cloud files (.e57, .las, .pts)
- Photogrammetric orthophotos and texture maps
- Triangulated meshes or surface reconstructions
- Georeferenced coordinate data for spatial alignment
Once processed, scan data enables precise measurement, comparison, and model generation in fields like construction, manufacturing, asset management, and infrastructure planning.
In architecture, civil engineering and industrial design, scan data is used for:
- As-built documentation of existing buildings and facilities
- Deformation monitoring in structures and earthworks
- Design validation against existing conditions
- Clash detection and retrofit planning
- Preservation of cultural heritage sites through high-fidelity 3D capture
The accuracy and completeness of scan data significantly reduce the need for on-site visits and manual measurements, increasing project efficiency and traceability.
