Popis:	Users prefer more realistic visualizations, even though they may be less efficient or even detrimental for a given task. In some previous studies, the evidence has shown that relief shading facilitates the landform interpretation while other studies have provided contrary results. In the present study, the effect of three different visualizations of elevation information on eye movements and performance was investigated in visual search, area selection, and route planning tasks. The results showed that the visualization of relief information affected the performance and eye movements in the visual search task. Overall, the eye movements differed between the search and area selection tasks, as well as between the search and route planning tasks. The result showed that the relief shading did not slow down the performance, either in terms of response time or eye movement measures.
