Pseudo-natural maps (also called natural-color maps) are topographic maps with a particularly vivid and comprehensible symbolization, uniting cartographic abstraction with natural appearance. Traditionally, this style can be found in manually created natural color relief representations and hand-painted landscape panoramas. The goal of this research is to formalize and extend these manual techniques in the form of computer graphics algorithms. The aim is to develop a more engaging and expressive map style that web mapping services can offer in addition to their traditional vector and satellite mapping modes.

Researcher: Jane Darbyshire
The goal of this project is to develop automatic and semi-automatic methods to create maps and other visualizations with pseudo-natural appearance.

Pseudo-natural maps have a long tradition in manual cartography in 2D and 3D, for example, as natural-color reliefs, winter maps and hand-painted panoramas. Such manual map creation is very time intensive and requires significant artistic talent. In digitally cartography, pseudo-natural map appearance is very rare, as specialized software for their creation is not available to cartographers.

Software will be developed to render pseudo-natural visualizations at various scales from OpenStreetMap data. The symbolization will be continuously adapted to local vegetation and climate zone.
