Unlike field parameters, where every point on the surface is taken into account in the calculation, the category of feature parameters takes into account only identified features on the surface. Features are considered because they play a significant role in a particular function (for example, large peaks and hills play a functional role as contact zones in mechanical engineering applications; while points located in valleys do not). Significant features are identified by segmentation of the surface and selected by a discrimination method known as pruning. Parameters are then calculated to quantify the characteristics of the selected features.

Results of an international survey are presented, detailing the use of surface texture parameters in industry. The survey received 179 responses from a total of 34 countries, revealing the use of a variety of parameters from ISO 4287, ISO 12085, ISO 13565-2/3 and ISO 25178. The survey responses show an increase in the number of users of profile parameters, and an increase in the range of surface texture parameters used, compared to the results from a similar survey in 1999, as well as a significant uptake of the new areal surface texture parameters. Individual sector usage is also discussed.
