Classical single-line elevation profiles often comprise some arbitrariness. Swath profiles can overcome this problem since the elevation values are considered not only along a line but along a swath. In a swath profile, the pixels are classified according to distance and statistical parameters (min, mean, max) of the classes are plotted against distance. The swath is usually a rectangular form but more irregular planforms are also possible. A special case is the "central swath", in which distance is calculated from a centre point. Besides some methodological development, this paper presents three case studies. In the first example, swath analysis is used to characterize the tilted surfaces found in the hilly landscape between the Ko{double acute}szeg Mts and the Rába river (in W Hungary and E Austria). Swath analysis also works for the more dissected western sections, thus proving the strength of this method. The second example discusses the Torockó (Trascǎu) Mts (in the eastern part of Apuseni Mts in Romania). Here, some water gaps and several wind gaps cross the karstic main ridge. Swath analysis helped to identify wind gaps not mentioned in previous publications and therefore it supports important data when outlining the drainage evolution of the area. Third, "central swath" profiles were used in order to numerically characterize the denudation of Central Andean volcanoes. The "ideal volcanic cone profile" is derived from the Parinacota volcano and this model enables comparisons to be made with older, more denuded volcanoes in order to quantify erosion volume.
