But what role does cartography play in the modern production of cartographic products? In this position paper, we will argue that the democratization and diffusion of cartographic production has also led to the presumed "fading relevance" of cartography. As an argument against this notion, we highlight starting points for the field of cartography to improve modern cartographic production through its inherent cartographic knowledge.}, subject = {Kartografie}, language = {en} } @inproceedings{MenzelBludauLeitneretal., author = {Menzel, Sina and Bludau, Mark-Jan and Leitner, Elena and D{\"o}rk, Marian and Moreno-Schneider, Juli{\´a}n and Petras, Vivien and Rehm, Georg}, title = {Graph Technologies for the Analysis of Historical Social Networks Using Heterogeneous Data Sources}, series = {Graph Technologies in the Humanities}, booktitle = {Graph Technologies in the Humanities}, editor = {Andrews, Tara and Diehr, Franziska and Efer, Thomas and Kuczera, Andreas and van Zundert, Joris}, address = {Wien}, organization = {Universit{\"a}t Wien}, issn = {1613-0073}, pages = {124 -- 149}, abstract = {Over the last decades, cultural heritage institutions have provided extensive machine-readable data, such as bibliographic and archival metadata, full-text collections, and authority records containing multitudes of implicit and explicit statements about the social relations between various types of entities.

Data visualization has assumed a central role in environmental journalism and is often used in data stories to convey the dramatic consequences of climate change and other ecological crises. However, the emphasis on the catastrophic impacts of climate change tends to induce feelings of fear, anxiety, and apathy in readers. Climate mitigation, adaptation, and protection—all highly urgent in the face of the climate crisis—are at risk of being overlooked. These topics are more difficult to communicate as they are hard to convey on varying levels of locality, involve multiple interconnected sectors, and need to be mediated across various channels from the printed newspaper to social media platforms. So far, there has been little research on data visualization to enhance affective engagement with data about climate protection as part of solution-oriented reporting of climate change. With this research we characterize the unique challenges of constructive climate journalism for data visualization and share findings from a research and design study in collaboration with a national newspaper in Germany. Using the affordances and aesthetics of travel postcards, we present Klimakarten, a data journalism project on the progress of climate protection at multiple spatial scales (from national to local), across five key sectors (agriculture, buildings, energy, mobility, and waste), and for print and online use. The findings from quantitative and qualitative analysis of reader feedback confirm our overall approach and suggest implications for future work.}, subject = {Erz{\"a}hlen}, language = {en} } @inproceedings{NagelDuval, author = {Nagel, Till and Duval, Erik}, title = {Muse}, series = {Proceedings of the 2nd International Workshop on Research 2.0. : At the 5th European Conference on Technology Enhanced Learning: Sustaining TEL}, volume = {675}, booktitle = {Proceedings of the 2nd International Workshop on Research 2.0. : At the 5th European Conference on Technology Enhanced Learning: Sustaining TEL}, publisher = {RWTH}, address = {Aachen}, issn = {1613-0073}, pages = {48 -- 52}, abstract = {This paper introduces Muse, an interactive visualization of publications to explore the collaborations between institutions.

With the rise of GPS tracking in various contexts such as smartphones and vehicles there has been a drastic increase in geospatial data being collect for personal reflection and organizational optimization. The generated movement datasets contain both geographical and temporal information, from which rich relational information can be derived. Common map visualizations perform especially well in revealing basic spatial patterns, but pay less attention to more nuanced relational properties. In contrast, network visualizations represent the specific topological structure of a dataset through the visual connections of nodes and their positioning. So far there has been relatively little research on combining these two approaches. Shifted Maps aims to bring maps and network visualizations together as equals. The visualization of places shown as circular map extracts and movements between places shown as edges, can be analyzed in different network arrangements, which reveal spatial and temporal topologies of movement data. We implemented a web-based prototype and report on challenges and opportunities about a novel network layout of places gathered during a qualitative evaluation.}, subject = {Karte}, language = {en} }
