- Abstract
Analytical geodashboards in a form of multiple, and typically coordinated views are meant to support the exploration of complex multivariate georeferenced data. Such interactive tools integrate several views presenting data with the use of different visualisation types, including maps. However, the visual and information complexity of geodashboards can be challenging for users, and properly designed explanatory elements should support them. Even though explanatory elements such as legend design for maps are guided by well established and empirically tested recommendations (e.g., Çöltekin et al. 2016, Dykes et al. 2010, Edler 2020, Gołębiowska 2015), these are not often applied in the design of analytical geodashboards. The advice of functional grouping, recommended by Schnürer et al. (2015) based on a single view atlas interface evaluation, suggests gathering all explanatory elements in one place within the interface. Although this advice is in line with the common legend solution applied in geographical atlases in which symbols from several maps are explained in one place, it contradicts the Gestalt principle on proximity that is often recommended for legend placement (Mayer 2001). As Horrower (2007) posits, violating this principle may result in split attention (i.e., the need for integrating information from different sources that may be a cognitive effort for users), since it results from, e.g., a spatial contiguity effect of materials separated by space. Therefore, to counteract this issue, one may split explanatory elements across the interface to locate their relevant parts close to corresponding views that need to be explained.
