Great Chishill Windmill
One of around eight surviving open trestle post mills, and the only one with a fantail, so it turned while we scanned it.

01 · Brief
A complete record of an 1819 post mill on its exposed trestle, inside and out, for a Trust that had brought it back from near collapse.
02 · Toolbox
- Terrestrial laser scanner
- UAV photogrammetry
- Terrestrial photogrammetry
- RealityScan
03 · On location
The fantail did its job all day. The whole mill kept turning to face the wind, so each scan and each photograph caught it in a different orientation. We treated the vanes, the sails, the trestle and the weatherboarded body as separate registrations and rebuilt the mill from its parts.
04 · Result
A textured model of interior and exterior, and a Gaussian splat of the mill in its fields from a selection of the drone and tripod images with the registered LiDAR.
