Building a record!
Drone photogrammetry is a highly effective method of Building Recording to inform the condition of a building or structure, and aid restoration work throughout a project.
In particular, the production of 2D orthographic images — which provide a detailed visual representation of the roofs and elevations — are an invaluable tool for building management.

3D Modelling
Our in-house geospatial specialists use photogrammetry to model buildings and structures, georeferenced to OS coordinates. The outputs include a 3D model and point cloud data, which can be combined with laser scanning to fill in high-level, out-of-reach places as part of a Measured Building Survey. These can be provided in a format compatible with Revit.

Orthographic Elevations
From the digital 3D model, we can generate orthorectified photos of the roofs and elevations. These are high-resolution, scaled and flattened photos which enable those working on the building, such as architects, to assess the condition of each elevation and pin-point areas of interest.

Stone-by-Stone Illustration
When extra detail is required in order to identify particular elements of a building, our in-house team can produce stone-by-stone illustrations. These illustrations can further inform architects and masons on the condition of a building.

Line Drawings
Where only basic levels of detail are required, line drawings from the orthographic elevations provide a simple outline of the subject.
