Recent developments and ubiquitous use of global positioning devices have revolutionised movement analysis, as we are able to collect increasingly larger movement data sets at increasingly smaller spatial and temporal resolutions. This talk discusses 3D representations of movement. We first introduce volumetric aggregations in a space-time cube (a conceptual 3D space, where the bottom two dimensions represent geographic space and the third dimensions time), the so-called space-time densities. The densities are used to visualise the dynamics of space use over time and to link movement with behavioural information obtained from other data (e.g. linking trajectories of eye and mouse in eye-tracking research and linking movement and behavioural data in marine animal tracking). In the second part of the talk we introduce a 3D volumetric algorithm for a geometric model of space use, the so-called potential path volumes and illustrate its use on real 3D trajectories. We finish the talk by outlining some of the open challenges for visual movement analytics.
About the Speaker
Dr Urška Demšar
at School of Geography & Sustainable Development at the University of St Andrews
Dr Urška Demšar is Senior Lecturer (Associate Professor) in Geoinformatics in the School of Geography & Sustainable Development at the University of St Andrews, Scotland, UK. She has a PhD in Geoinformatics from the Royal Institute of Technology (KTH), Stockholm, Sweden and a background in Applied Mathematics from the University of Ljubljana, Slovenia. Her research interests are in spatio-temporal visual analytics and in particular in visualisation and analysis of movement – a topic on which she is collaborating with movement researchers from other disciplines (movement ecologists, human-computer interaction specialists). She established these interdisciplinary collaborations through her participation in the European COST Action MOVE (Knowledge Discovery from Moving Objects). She is currently Associate Editor of the International Journal of Geographical Information Science and in the period 2015-2019 she was co-chair of the International Cartographic Association commission on Visual Analytics (http://viz.icaci.org). You can find her online at http://udemsar.com and on Twitter as @udemsar.
