Abstract
Geotechnical logging of drillcore typically includes joint roughness due to its importance in rock mass characterisation. Here we propose digitising the measurement of roughness via a tomography scan. Image processing steps are described for relating the scan to a simple profilometric definition of roughness. The approach is amenable to directional statistical visualisation on a stereoplot.
