York Archaeological Trust has an in-house capacity to conduct laser scan surveys and to process this data to produce 3D models. We have laser scanners capable of recording buildings and landscapes as well as laser scanners to record artefacts. Digital processing of this data is also done in-house creating 3D models for visualisation purposes by constructing entire archaeological sites in the virtual environment. Our artefact scanners are capable of capturing very fine details, generating models suitable for the 3D printing of museum artefacts.

FAQ on Digital Mapping
- How does 3D mapping work?
3D mapping utilises the latest digital technology to create a virtual copy of an object, building or archaeological site. This process can involve the use of an instrument such as a laser scanner which collects hundreds of thousands of points per second across the surface of an object, building or landscape. This data is called a pointcloud and it is an accurate measured record of the subject that has been scanned. Multiple pointclouds can be combined to create a complete virtual copy of the subject within the computer.
- Can anything be digitally scanned?
Most objects, buildings and landscapes can be scanned, but each subject will have its own difficulties. Common issues are with highly reflective objects which do not scan very well. The application of a fine dust can overcome reflective problems. Every subject is unique so it is best to have a 3D recording approaching designed for the specific task. Utilising several technologies allows us to tailor our methods to acquire the best possible 3D record of a unique subject.
- How can a digital scan help me?
Creating a digital copy of a subject allows for limitless possibilities. It is an accurate copy of the subject which can be shared with anyone you wish to. This might be as a simple 3D model or as a web based portal. The digital data has the potential to give an audience access to the subject which without the scans might not otherwise have been possible. This data can be 3D printed as a replica to any scale or it can printed for distribution as a hologram for exhibitions and demonstrations. The data can be examined in detail with sophisticated visualisation techniques, new discoveries about the subject are often made simply by examining the scan data.
