On Ortho-Radial Drawings for Metro Networks

VCLA hosted a talk by Benjamin Niedermann

ABSTRACT

Metro maps are schematic maps illustrating metro networks of cities. In contrast to road maps, the focus lies on the visualization of the network topology rather than on the geographic rendering of the network. Hence, when drawing a metro network, the algorithmically complex problem of finding a good network layout arises. Lately, concentric circles maps of metro networks have gained attention. Such drawings can be considered as grid drawings in the plane, where the grid is formed by concentric circles and straight-line spokes emanating from the circles' center. In this talk we present first steps towards an approach for automatically generating such ortho-radial drawings of metro networks.
