This quadrangular, timber-framed Rowan well, excavated in the former Roman vicus of Harelbeke (Belgium), was one of the first 3D models we’ve made on an excavation. The excavations were conducted by GATE bvba in 2011. The recording was done to assess the possibilities (and limitations) of image-based 3D modelling for the documentation of archaeological features. The well was recorded with 104 photographs. The 3D model was georeferenced with 13 ground control points, resulting in a RMSE of 0.023m. The illustration shows a vertical orthoimage derived from the 3D model (right), and a digital drawing based on the orthoimage (left).
