Stylus Data on Polar Style White (PSW) These are commercial flooring tiles. The model of the tile is given in the name of the Digital Surface Twin. The manufacturer and some additional details can be found in the associated publication (see below). Surface topography data for these tiles were collected on a stylus profilometer (DektakXT, Bruker, Billerica, Massachusetts, USA). The measurements were collected with random orientations with respect to the tile edges and did not show any significant variation with direction. This data is associated with the following publication: A.B. Randolph, K. Reifler, V. Chadha, T.D.B. Jacobs, K.E. Beschorner, The need for better metrics for floor-tile topography: Conventional metrics correlate only modestly with shoe-floor friction.
