Spatio Temporal Density Mapping of a Dynamic Phenomenon
Stefan Peters, Liqiu Meng · mediaTUM (Technical University of Munich) · 2014
Visualizing density and distribution information is a key support for understanding spatio-temporal phenomena represented by point data. However, the temporal information is not yet adequately handled in existing density map approaches. In this paper, we propose a novel approach for the creation of a 2D density surface - using contour intervals - for dynamic points or phenomena. Our method is based on a rainbow color scheme, which enables the user to visually extract spatio-temporal changes of point density and distribution. Furthermore, we present various possibilities for extending and improving our approach.
