The role of hill-shading in tourist maps (original) (raw)
The paper is focused on eye-tracking evaluation of two variants of Czech online tourist maps. Terrain in the first type of maps was depicted with contour lines and elevation points only. In the second type of maps, visualization was enhanced by hill-shading. The purpose of the case study was to evaluate if the hill-shading helps users with better imagination of the terrain. The experiment was complemented with a short questionnaire focused on users' subjective opinion about suitability and aesthetics of both map types. The task was to find out one particular place (village or hill) in the map as fast as possible and mark it with the mouse. Two aspects were investigated - if hill-shading helps users to find the hill, and at the same time, if the hill-shading make it more difficult to find the village. The data were analysed statistically and with the use of visual analytics methods. Preliminary results denotes that respondents prefer shaded maps from the aesthetics point of view, but there is no statistically significant difference for any of used eye-tracking metrics. The results of the study will answer the question, if hill-shading used in tourist maps helps users to perceive the terrain better.
