A methodological inquiry for anchoring pan-scalar maps

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.
