“…From a cognitive perspective, the way our vision and our brain work might also explain this disorientation and the desert fog effect. Change blindness [91] might be one cause of disorientation as vision focuses on specific parts of the map during a zoom [97], and the map reader might be blind to changes elsewhere in the map. Inattentional blindness is another significant cognitive effect that makes us blind to some details when we have to focus our vision on too many objects [66], which is the case when the map is changing too much during a zoom.…”

When you zoom in or out of current multi-scale cartographic applications, it is common to feel lost and disoriented for a few seconds because dimensions and map symbols have changed. To make the exploration of these multi-scale maps more fluid, one option is to design maps where the transformations due to scale change are more progressive. This paper proposes to use cartographic generalization techniques to design these multi-scale maps with additional intermediate scales to improve progressiveness. These more progressive maps are tested in a user study with a task requiring multiple zooms in and out. The users perform better with the progressive maps, and in particular, the total quantity of required zooming is reduced compared to maps without additional intermediate scales. However, the survey is not fully conclusive on task performance due to the complexity of such a survey with real maps. This difficulty in assessing how well progressive map generalisation reduces disorientation is discussed and guidelines are proposed to design further studies.

“…These significant map elements are referred to as pan-scalar anchors, by analogy with the anchor theory in spatial cognition (Couclelis et al, 1987). A recent eye-tracking study supported the idea that users look at pan-scalar anchors before, during, and after a zoom (Wenclik and Touya, 2023).…”

Abstract. This paper reports two experiments for the design of anchored pan-scalar maps. Anchoring pan-scalar maps means improving the saliency and memorability of some cartographic elements, i.e. the pan-scalar anchors, to enhance the navigational cues that can be used for self-localization during or after a zoom in a map. Within this article, concrete examples illustrate the process of adding anchors at different locations in the map, or how map designers can extend the scale range where anchors are salient. The paper concludes by highlighting the practical implications of this research for mapping professionals, offering a clear path for the creation of more effective anchored pan-scalar maps.
