However, relatively little research has focused on the visual overviews themselves, and their potential impacts on EDA outcomes. In a user study, we evaluated the influence of different levels of domain knowledge on the usefulness of four distinct types of static visual overview of spatiotemporal data. Beyond simply orienting users, our results indicate that visual overviews can be important in gaining insights into a data set, for example, in learning about metadata. Although subjects without domain knowledge struggled to judge the quality of their findings, they were as successful at identifying interesting patterns in the data as those with domain expertise. Our results suggest that detailed background knowledge of a data set can actively hinder EDA. Being already familiar with their own data sets, our results highlight the tendency of data experts to disregard findings that do not match their pre-existing domain knowledge. Based on these findings, our conclusions identify a range of potential avenues for future work, including the use of visual overviews that deliberately do not, from first view, reveal the context of the data they show. This later approach could help in cases where domain experts need to see their data with ‘fresh eyes’, and detect interesting patterns in spatiotemporal data before relating the findings to specific knowledge about the data sets and the domain.

Quality control and new data-quality measures for the aesthetics of a Croatian topographic map at the scale of 1:25,000 / Branko Puceković in International journal of cartography, vol 3 n° 2 (December 2017)

As the topic of the aesthetics of the topographic map has, in the authors’ opinion, not been extensively covered, the paper concentrates on this topic. The paper focuses on devising an aesthetic standard relating mainly to the representation of relief. In fact, aesthetics can be controlled indirectly in terms of relief and water course alignment, the smoothness of contour lines, the non-existence of bonded contour lines and rock representation justification. A comparison between quality control at the CGI and quality elements according to contemporary standards was carried out. The presence of data-quality elements was registered in accordance with the ISO guidelines. A proposal for several data-quality measures for aesthetics related to relief representation is also given.
