Abstract: In a system that uses tile-based road network rendering for displaying map information to a user, a tile is rendered for display by rendering a front tile (20) with an appropriate texture to depict, e.g., the “ground” and a see-through shape (22) representing a feature that is below the ground level, and rendering a rear tile (21) that has drawn on it an image region (23) representing the intended below ground level feature, surrounded by a color or texture (24) that represents a border for that feature, to appear behind and slightly offset relative to the front tile (20), such that the image region (23) and its corresponding border (24) on the rear tile (21) can be seen through the see-through shape (22) in the front tile (20). In this way, a more visually appealing depiction of the below ground level feature can be achieved.
