What photogrammetry is Photogrammetry is the process of extracting 3D information from 2D photographs. By capturing a site from hundreds of different angles, software can triangulate the position of millions of points to build a "Digital Twin" of the environment.
Typical outputs - **3D Mesh**: A photorealistic textured model of the site or building. - **Point Cloud**: A set of millions of X,Y,Z coordinates used by surveyors and engineers. - **DSM/DTM**: Digital Surface and Terrain Models showing the topography of the land. - **Orthomosaic**: A measurable high-resolution aerial map.
Accuracy considerations Professional photogrammetry is far more than just "flying a drone." It requires careful flight path planning, high-overlap capture, and the use of RTK or GCPs to ensure the resulting model matches the real world to within centimetres.
Uses in construction, property and heritage - **Construction**: As-built vs As-designed comparisons. - **Property**: Creating immersive 3D records of assets for management and marketing. - **Heritage**: Digitally preserving listed structures in high detail for future generations.
Integration into BIM and CAD Our outputs are compatible with major industry software including Autodesk Revit, Civil 3D, Navisworks, and ArcGIS, allowing for seamless integration into your existing technical workflows.
Practical Considerations
— Drone operations are subject to airspace, weather, site access, permissions, nearby people and property, and operational safety requirements.
