Panorama maps are stylized paintings of terrain often seen at tourist destinations. They are difficult to create since they are both artistic and grounded in real geographic data. In this paper we present techniques for rendering real-world data in the style of Heinrich Berann's panorama maps in a real-time application. We analyze several of Berann's paintings to capture the conventions used for form, shape, projection, colour, and texture. We use this analysis to form algorithms that mimic the style of the panorama map, focusing on replicating the terrain deformation, distorted projection, terrain colouring, tree brush strokes, water rendering, and atmospheric scattering. In our approach, we use freely available digital earth data to render interactive panorama maps without any further design work necessary.
