Photogrammetry
We are photogrammetry specialists or even photogrammetrists, we produce high resolution, accurate and visually stunning 3d meshed models for heritage, survey and asset management.
Now often referred to as reality capture or even digital twins, we have the expertise to apply photogrammetry techniques to a wide range of objects, whether it’s a large site or small highly detailed artifacts, here at WGP Digital we have the knowledge and experience to provide effective solutions.
The use of drones/UAVs has enhanced the photogrammetry process and deliverables. This method is now included in nearly all of our measured building surveys, the data is so useful to help in producing a high quality and detailed product.
Below is a very small selection of our work, in particular please take a look at a high quality model which is viewable via the powerful nira.app website.

Reality capture examples
Video clip of 3D reality capture model of St. Hubbert’s Church – a mixture of aerial and ground based imagery, zoomed in detail towards the end…
Please note that this is a 3d meshed model – the video zooms in towards the end showing the level of detail achieveable!
Photogrammetry uses
- Topographic surveys using a drone/UAV – especially for large areas, quarries etc. Where ‘feet on the ground’ surveys are too time consuming or difficult to reach.
- 3d models of artifacts – high resolution models of artifacts, accurate and realistic. See my case study on the Minerva Temple where this method was put to great use.
- 3d models of buildings – for internal or external uses, ground imagery can be combined with a drone/UAV to produce a point cloud/3d mesh.
- Rectified photography – again using a combination of ground and drone imagery produce high resolution rectified photographs, read more…
- Visualisations – for photorealistic visualisation schemes.
- 3d meshed models or 3d point clouds for 3d environments – gaming and virtual reality.
- 3d high quality models for asset management.
- Base models for production of roof plans, elevations etc.
“Photogrammetry is the art and science of extracting 3D data from photographs. The process involves taking overlapping photographs of an object, structure, or space, and converting them into 2D or 3D digital models.”

FAQ
Millimetre accuracy is achieveable for small models or buildings – but dependant on comprehensive control or grid, however large schemes, sites etc the accuracy will decrease to centimetres.
In most cases it can be a more cost effective solution than laser scanning or boots on the ground survey. Worth discussing the project objectives to determine the most efficient solution.
