Measured building surveying, but with higher resolution 3D scanning and photogrammetry. Every stone can be measured, digitized, 3D modelled and drawn in 2D. Photogrammetry is the extraction of 3-dimensional measurements from 2-dimensional photographic images. Superior detail can be recorded.

The Chapel, Heaton Cemetery, Bolton. Now demolished, but here digitally preserved. Planning applications to demolish require existing drawings as a record. We rendered orthographic projections of the scan data and cut floor plan slices instead of producing time-consuming CAD line work drawings.
