METHODS OF AND APPARATUS FOR DISPLAYING MAP INFORMATION

摘要

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 tile (10) by using a first texture comprising one or more map features to be displayed for the tile of the map in combination with a second texture to apply a texture to a graphics primitive or primitives representing the tile such that at least one map feature (11), such as a water feature, being displayed on the tile (10) is bordered by a border region (24) that represents a border to that map feature. In this way, a more visually appealing depiction of the map feature (11) can be achieved.
