In this fully open access paper, Michael Getzner, Barbara Faerber and Claudia Yamu compare 2D versus (stereoscopic) 3D landscape visualisations of different landscape scenarios in the Alps. Although there have been previous studies of landscape visualizations of alpine scenarios, I found that this paper is adding a couple of particularly new perspectives: a) the use of stereoscopic (anaglyph) visualisations and b) the link to the economic valuation of different landscapes through the participants. It should be said that this study like many others was conducted with students. However, I think it provides the legitimization to use landscape visualisations for other studies on the economic valuation of such landscapes.
