Practical Geo Scan guidance on Heritage Photogrammetry 3D Laser Scanning for architects, developers and project teams.
A heritage reality-capture workflow should be scoped around the decision the project team needs to make.
Surveyors establish safe access, control, scanner positions and photographic coverage around the asset, including facades, interiors, roof areas, performance spaces or detailed artefacts where required.
Survey control and registration checks keep the scan, image and drawing outputs consistent, auditable and suitable for design or conservation use.
Point clouds, photographic sets and orthographic outputs are processed into usable datasets, with unwanted movement, noise and duplicate coverage managed before issue.
The dataset is checked for coverage, alignment, scale, completeness and suitability for the agreed deliverables.
Outputs may include point clouds, CAD elevations, measured drawings, orthographic imagery, textured 3D models, BIM references and archive-grade visual records.
Registered point clouds: Controlled 3D survey data for geometry, coordination and measured drawing production.
Measured drawings: Plans, elevations and sections that reflect the real geometry of historic or irregular fabric.
Orthographic imagery: Rectified facade, ceiling, floor or detail imagery for review, annotation and condition records.
Photogrammetry models: Textured 3D records for artefacts, stonework, interiors, exhibition elements or digital interpretation.
Geo Scan scopes heritage reality capture around the project outcome first: conservation record, design coordination, measured drawing package, BIM reference, visual archive or digital interpretation.
