  • Narrative of the annotated Space – Time Cube – revisiting a historical event

    • Authors: Kveladze, I.; Kraak, M.J.;  Advisor: -;  Participants: - (2017)

  • The Space–Time Cube (STC) is a suitable representation to display multiple characteristics of movement data and will especially reveal temporal patterns in the data. By adding annotations to the cube’s paths and stations, the narrative of the display is enhanced. To illustrate the STC’s storytelling capabilities, a historical event, Napoleon’s crossing of the Berezina River during his Russian campaign in 1812 is presented and linked to an event in 2012 when the authors made a similar trip. Also, a set of different visual queries and their results are presented, emphasizing the STC as an alternative addition to a more extended visualization environment.

  • Of maps, cartography and the geography of the International Cartographic Association

    • Authors: Fabrikant, S.I.; Kraak, M.J.;  Advisor: -;  Participants: - (2017)

  • In this contribution, we first focus on maps as landmarks of cartographic innovation in the context of societal and technical developments in history. We then turn to cartography itself, by analyzing the sustainability of past and current disciplinary definitions, as proposed by its leading professional body, the International Cartographic Association (ICA). In the fourth section, we then go on to analyze the structure and activities of the ICA over the recent past, with the aim to further understand the professional development of the cartographic discipline. Finally, we also consider how the geography of the ICA.

  • Revisiting flow maps : A classification and a 3D alternative to visual clutter

    • Authors: Kraak, M.J.; Gu, Y.;  Advisor: -;  Participants: - (2017)

  • Flow maps have long been servicing people in exploring movement by representing origin-destination data (OD data). Due to recent developments in data collecting techniques the amount of movement data is increasing dramatically. With such huge amounts of data, visual clutter in flow maps is becoming a challenge. This paper revisits flow maps, provides an overview of the characteristics of OD data and proposes a classification system for flow maps. For dealing with problems of visual clutter, 3D flow maps are proposed as potential alternative to 2D flow maps.
