- alternative raster systems: non-orthogonal, radial, concentric, spiral
- coexistence/overlay of different raster systems: (controlled with a kind of mapped area plan)
- transport infrastructure: city highways, railways
- geographic globals: hills, river, lakes
- city green spaces: parks, trees (schematic)
