While graphic variables in 2D maps have been extensively investigated, 4D cartography is still a widely unexplored field. In this paper we investigate the usefulness of 4D maps (3 spatial dimensions plus time) for cartographically illustrating spatio-temporal environmental phenomena. The presented approach focuses mostly on explorative research rat...
