Methods of and apparatus for displaying map information

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.
